If a match is not found, a basis file from one of the DIRs will be selected to try to speed up the transfer. If DIR is a relative path, it is relative to the desti- nation directory. See also --copy-dest and --link-dest. NOTE: beginning with version 3. This is useful for doing transfers to a new destination while leaving existing files intact, and then doing a flash-cutover when all files have been successfully transferred.
Multiple --copy-dest directories may be provided, which will cause rsync to search the list in the order speci- fied for an unchanged file. See also --compare-dest and --link-dest.
The files must be identical in all pre- served attributes e. Also check if some attributes are getting SunOS 5. If a match is found that differs only in attributes, a local copy is made and the attributes updated. This option works best when copying into an empty des- tination hierarchy, as existing files may get their attributes tweaked, and that can affect alternate des- tination files via hard-links. Also, itemizing of changes can get a bit muddled.
Note that prior to ver- sion 3. Note that if you combine this option with --ignore-times, rsync will not link any files together because it only links identical files together as a substitute for transferring the file, never as an addi- tional check after the file is updated.
See also --compare-dest and --copy-dest. Note that rsync versions prior to 2. You can work-around this bug by avoiding the -o option when sending to an old rsync. Note that this option typically achieves better com- pression ratios than can be achieved by using a com- pressing remote shell or a compressing transport because it takes advantage of the implicit information in the matching data blocks that are not explicitly SunOS 5.
See the --skip-compress option for the default list of file suffixes that will not be compressed. If NUM is non-zero, the --compress option is implied. You may specify an empty string to indicate that no file should be skipped.
Simple character-class matching is supported: each must consist of a list of letters inside the square brackets e. By default rsync will use the username and groupname to determine what ownership to give files.
If a user or group has no name on the source system or it has no match on the destination system, then the numeric ID from the source system is used instead.
See also the comments on the "use chroot" setting in the rsyncd. Note that the sender's name for the 0 user and group are not transmitted to the receiver, so you should either match these values using a 0, or use the names in effect on the receiving side typically "root". All other FROM names match those in use on the sending side.
All TO names match those in use on the receiving side. This means that you will need to specify numeric FROM values if you want to map these nameless IDs to different values. For the --usermap option to have any effect, the -o --owner option must be used or implied , and the receiver will need to be running as a super-user see also the --fake-super option. For the --groupmap option to have any effect, the -g --groups option must be used or implied , and the receiver will need to have permissions to set that group.
This is a simpler interface than using --usermap and --groupmap directly, but it is imple- mented using those options internally, so you cannot mix them.
If no data is transferred for the specified time then rsync will exit. The default is 0, which means no timeout. If the timeout is reached, rsync exits SunOS 5. The --address option allows you to specify a specific IP address or host- name to bind to. See also this option in the --daemon mode section.
This is only needed if you are using the double-colon :: syntax to connect with an rsync daemon since the URL syntax has a way to specify the port as a part of the URL. You can set all sorts of socket options which may make transfers faster or slower! Read the man page for the setsock- opt system call for details on some of the options you may be able to set.
By default no special socket options are set. This only affects direct socket con- nections to a remote rsync daemon. This option also exists in the --daemon mode section. You may specify as little as a single letter for the mode, and use upper or lower case. The main use of this option is to change Full buffering SunOS 5. If you repeat the option, unchanged files will also be output, but only if the receiving rsync is at least version 2.
The general format is like the string YXcst- poguax, where Y is replaced by the type of update being done, X is replaced by the file-type, and the other letters represent attributes that may be output if they are being modified. The file-types that replace the X are: f for a file, a d for a directory, an L for a symlink, a D for a device, and a S for a special file e. The attribute that is associated with each letter is as follows: o A c means either that a regular file has a differ- ent checksum requires --checksum or that a sym- link, device, or special file has a changed value.
Note that if you are sending files to an rsync prior to 3. Note: when using an rsync 3. For a full list of the possi- ble escape characters, see the "log format" setting in the rsyncd.
Rsync will output the out-format string prior to a file's transfer unless one of the transfer-statistic escapes is requested, in which case the logging is done at the end of the file's transfer.
When this late log- ging is in effect and --progress is also specified, rsync will also output the name of the file being transferred prior to its progress information fol- lowed, of course, by the out-format output. If specified as a client option, transfer logging will be enabled SunOS 5. See the --log-file-format option if you wish to override this. If you specify an empty string, updated files will not be mentioned in the log file. For a list of the possible escape characters, see the "log format" setting in the rsyncd.
The current statistics are as follows: o Number of files is the count of all "files" in the generic sense , which includes directories, symlinks, etc. The total count will be followed by a list of counts by filetype if the total is non-zero. For example: " reg: 5, dir: 3, link: 2, dev: 1, special: 1 " lists the totals for regu- lar files, directories, symlinks, devices, and special files. If any of value is 0, it is com- pletely omitted from the list.
The total count will be followed by SunOS 5. Note that this line is only output if deletions are in effect, and only if protocol 31 is being used the default for rsync 3. Note that rsync 3. This does not count any size for directories or special files, but does include the size of symlinks. This is smaller than the in-memory size for the file list due to some compressing of duplicated data when rsync sends the list.
This requires a modern rsync on the sending side for this to be present. All control characters but never tabs are always escaped, regardless of this option's setting. The escape idiom that started in 2. A literal backslash that is in a filename is not escaped unless it is followed by a hash and 3 digits There are 3 possible levels: 1 output numbers with a sepa- rator between each set of 3 digits either a comma or a period, depending on if the decimal point is repre- sented by a period or a comma ; 2 output numbers in units of with a character suffix for larger units -- see below ; 3 output numbers in units of The default is human-readable level 1.
Each -h option increases the level by one. You can take the level down to 0 to output numbers as pure digits by specif- ing the --no-human-readable --no-h option. The unit letters that are appended in levels 2 and 3 are: K kilo , M mega , G giga , or T tera. For example, a byte file would output as 1. Backward compatibility note: versions of rsync prior to 3. Thus, specifying one or two -h options will behave in a comparable manner in old and new versions as long as you didn't specify a --no-h option prior to one or more -h options.
See the SunOS 5. In some circum- stances it is more desirable to keep partially trans- ferred files. Using the --partial option tells rsync to keep the partial file which should make a subsequent transfer of the rest of the file much faster. On the next transfer, rsync will use a file found in this dir as data to speed up the resump- tion of the transfer and then delete it after it has served its purpose. Note that if --whole-file is specified or implied , any partial-dir file that is found for a file that is being updated will simply be removed since rsync is sending files without using rsync's delta-transfer algorithm.
Rsync will create the DIR if it is missing just the last dir -- not the whole path. If the partial-dir value is not an absolute path, rsync will add an exclude rule at the end of all your exist- ing excludes. This will prevent the sending of any partial-dir files that may exist on the sending side, and will also prevent the untimely deletion of par- tial-dir items on the receiving side.
An example: the above --partial-dir option would add the equivalent of "-f '-p. For instance, if you want to make rsync clean-up any SunOS 5. Avoid using --delete-before or --delete-during unless you don't need rsync to use any of the left-over partial-dir data during the current run.
Setting this in the environment does not force --partial to be enabled, but rather it affects where partial files go when --partial is specified. The only times that the --partial option does not look for this environment value are 1 when --inplace was specified since --inplace conflicts with --partial-dir , and 2 when --delay-updates was specified see below.
For the purposes of the daemon-config's "refuse options" setting, --partial-dir does not imply --par- tial. This is so that a refusal of the --partial option can be used to disallow the overwriting of des- tination files with a partial transfer, while still allowing the safer idiom provided by --partial-dir.
This attempts to make the updating of the files a little more atomic. By default the files are placed into a directory named ". See the comments in the --partial-dir section for a discussion of how this ". Conflicts with --inplace and --append. This option uses more memory on the receiving side one bit per file transferred and also requires enough free SunOS 5.
Note also that you should not use an absolute path to --partial-dir unless 1 there is no chance of any of the files in the transfer having the same name since all the updated files will be put into a single directory if the path is absolute and 2 there are no mount points in the hierarchy since the delayed updates will fail if they can't be renamed into place.
See also the "atomic-rsync" perl script in the "sup- port" subdir for an update algorithm that is even more atomic it uses --link-dest and a parallel hierarchy of files. Note that the use of transfer rules, such as the --min-size option, does not affect what goes into the file list, and thus does not leave directories empty, even if none of the files in a directory match the transfer rule.
Because the file-list is actually being pruned, this option also affects what directories get deleted when a delete is active. However, keep in mind that excluded files and directories can prevent existing items from being deleted due to an exclude both hiding source files and protecting destination files.
See the per- ishable filter-rule option for how to avoid this. You can prevent the pruning of certain empty directo- ries from the file-list by using a global "protect" filter. This gives a bored user something to watch. These statistics can be misleading if rsync's delta-transfer algorithm is in use. For example, if the sender's file consists of the basis file followed by additional data, the reported rate will probably drop dramatically when the receiver gets to the literal data, and the transfer will probably take much longer to finish than the receiver estimated as it was finish- ing the matched part of the file.
In an incremental recursion scan, rsync won't know the total number of files in the file-list until it reaches the ends of the scan, but since it starts to transfer files during the scan, it will display a line with the text "ir-chk" for incremental recursion check instead of "to-chk" until the point that it knows the full size of the list, at which point it will switch to using "to-chk".
Thus, seeing "ir-chk" lets you know that the total count of files in the file list is still going to increase and each time it does, the count of files left to check will increase by the number of the files added to the list. Its purpose is to make it much easier to specify these two options for a long transfer that may be inter- rupted. Use this flag without outputting a filename e. The file should contain just the password on the first line all other lines are ignored.
Rsync will exit with an error if FILE is world readable or if a root-run rsync command finds a non-root-owned file. This option does not supply a password to a remote shell transport such as ssh; to learn how to do that, consult the remote shell's documentation. When SunOS 5. This option is inferred if there is a single source arg and no destination speci- fied, so its main uses are: 1 to turn a copy command that includes a destination arg into a file-listing command, or 2 to be able to specify more than one source arg note: be sure to include the destination.
Caution: keep in mind that a source arg with a wild-card is expanded by the shell into multiple args, so it is never safe to try to list such an arg without using this option. By default they will contain digit separators, but higher levels of readability will output the sizes with unit suffixes. Note also that the column width for the size output has increased from 11 to 14 charac- ters for all human-readable levels. Use --no-h if you want just digits in the sizes, and the old column width of 11 characters.
Compatibility note: when requesting a remote listing of files from an rsync that is version 2. If no suf- fix is specified, the value will be assumed to be in units of bytes as if "K" or "KiB" had been appended. See the --max-size option for a description of all the available suffixes.
A value of zero speci- fies no limit. For backward-compatibility reasons, the rate limit will be rounded to the nearest KiB unit, so no rate smaller than bytes per second is possible. Rsync writes data over the socket in blocks, and this option both limits the size of the blocks that rsync writes, and tries to keep the average transfer rate at the requested limit.
Some "burstiness" may be seen where rsync writes out a block of data and then sleeps to bring the average rate into compliance. Due to the internal buffering of data, the --progress option may not be an accurate reflection on how fast the data is being sent. This is because some files can show up as being rapidly sent when the data is quickly buffered, while other can show up as very slow when the flushing of the output buffer occurs.
This may be fixed in a future version. This lets you transport the changes to the destination system via some other means and then apply the changes via --read-batch.
Note that you can feel free to write the batch directly to some portable media: if this media fills to capacity before the end of the transfer, you can just apply that partial transfer to the destination and repeat the whole process to get the rest of the changes as long as you don't mind a partially updated destination sys- tem while the multi-update cycle is happening. If FILE is -, the batch data will be read from standard input. This is useful for creating a batch file that is compatible with an older version of rsync.
For instance, if rsync 2. This order ensures that the option will stay the same whether you're pushing or pulling files. For a list of what charset names your local iconv library supports, you can run "iconv --list". If you specify the --protect-args option -s , rsync will translate the filenames you specify on the com- mand-line that are being sent to the remote host.
It is up to you to ensure that you're specifying matching rules that can match on both sides of the transfer. When you pass an --iconv option to an rsync daemon that allows it, the daemon uses the charset specified in its "charset" configuration parameter regardless of the remote charset you actually pass. Thus, you may feel free to specify just the local charset for a daemon transfer e. This only affects sockets that rsync has direct control over, such as the outgoing socket when directly con- tacting an rsync daemon.
See also these options in the --daemon mode section. If rsync was complied without support for IPv6, the --ipv6 option will have no effect. The --version out- put will tell you if this is the case. This 4 byte checksum seed is included in each block and MD4 file checksum calculation the more modern MD5 file check- sums don't use a seed. By default the checksum seed is generated by the server and defaults to the current time.
This option is used to set a specific check- sum seed, which is useful for applications that want repeatable block checksums, or in the case where the user wants a more random checksum seed.
Setting NUM to 0 causes rsync to use the default of time for check- sum seed. The daemon you start running may be accessed using an rsync SunOS 5.
If standard input is a socket then rsync will assume that it is being run via inetd, otherwise it will detach from the current terminal and become a back- ground daemon.

If so, how do I get it running as a daemon? I want to copy files from remote Linux system to my laptop using SSH client. I use XShell for ssh. Now in my local machine i. Use the WinSCP windows tool and connect to a remote Linux system and transfer files to your local windows.
Does this make difference? Trying to back up a VPS on a home computer running Windows. As I understand this will be done via SSH. Using Backup Agent 6. I either have to do more to sync it or there is an error in the path to the VPS.
How do I prove the path to get the volume to be recognized or otherwise synchronize with everything? Show Posts. Using Rsync as root in Solaris 11 for DR.
Registered User. Join Date: Jan Hi, I am working on a Solaris 11 server for the first time and am trying to set up the DR server.
Usually I use trusted rsync between Production and DR to copy changed files to the latter, but this doesn't seem possible now that root is a role. I want to copy things like the password, group files plus home directories and some other files. They are reasonably substantial, so I only want to transfer changed files rather than all of them.
Does anyone have a solution for this without changing root back to a normal user and thereby reducing security? Needless to say my client wouldn't be keen on reduced security.
Thanks in advance. Join Date: Mar How about sending a zfs stream to DR site, on some other pool beside rpool and then copying what you require from that? Then copy the required files you want to keep.
This script creates log as well with newly synchronized files information. Run the script manually. Verify the log file. Create a new file to sync the data to mylinz2 server. Verify the whether the newly created file synced in mylinz2. Our rsync script is working fine. If you want to sync the data between two servers automatically on preferred time interval,you can add the script in to crontab.
