rdup-mirror(8) - Linux man page

Name

rdup-mirror - mirror the files from the list on standard input

Synopsis

rdup-mirror [ OPTIONS ]

Description

rdup-mirror copies the files it gets from standard input to the directory specified with the -b option. This script implements the backup policy.

If a file already exists in the backup directory it will be moved and will get a suffix. This suffix is of the form: '+DD.HH:MM'. This suffix is thus accurate to the minute. Multiple changes to files within one minute are never caught by rdup-mirrorl.

Option

-a
Write the uid and gid information to the file's extended user attributes: 'r_uid' and 'r_gid'. This option only works if attr is available on the system. This currently works on Linux and Solaris 10.

This option is usefull when storing a remote backup. Normally these backups are transferred by a non-root user. This user will not be able to correctly set all uid/gid information. As a workaround rdup-mirror will set the extended user attributes to the uid/gid as it got them from standard input.

-b backupdir
Store the backup in backupdir. This argument is mandatory.
-c
Used in conjunction with rdup's -c. This will allow rdup-mirror to be used for remote backups.
-R
Restore mode. Always write the file to the target directory and don't rename existing files to a +DD.HH:MM suffix.
-v
Echo the files processed to standard error.
-h
Short help message.
-V
Show the version.
