rdup-snap(1) - Linux man page

Name

rdup-snap - create backup in a hard link directory

Synopsis

rdup-snap [ OPTION ]

Description

rdup-snap copies the files it gets from standard input to the directory specified with the -b option. This script implements the backup policy. It works on a directory that is hard linked or on an empty directory. When the directory is empty a full dump is performed.

If a file (i.e. hard link) already exists in the backup directory it will be removed. The end result will be that you will be left with a complete mirror of your directory structure at the time of the backup. Due to the use of hard links the amount of disk space used for the backup is minimized.

Options

-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 for Linux and Solaris 10.
-b backupdir
Store the backup in backupdir. This argument is mandatory.
-R
Restore mode. Copy the files from standard input to the directory given with the -b option. In restore mode all entries which should be removed are ignored and no overview message at the end of the restore is given.
-c
Used in conjunction with rdup's -c. This will allow rdup-snap to be used for remote backups.
-p NUM
Strip NUM slashes of the path names, thereby stripping a common prefix of all names. Only valid when -R is also given.
-v
Echo the files processed to standard error.
-h
Short help message.
-V
Show the version.
