Ubuntu Manpage: rdup-simple - create a hardlinked backup

NAME

       rdup-simple - create a hardlinked backup

SYNOPSIS

       rdup-simple [+DAYS] -[-P CMD]...  [OPTION]...  FILELIST [DIR/FILE]...  DESTINATION

DESCRIPTION

rdup-simple is a frontend for 'rdup-snap' and 'rdup'. It will backup all directories and files given on
the command line. It will create a hard linked backup directory, where the backup is created. With the
optional +DAYS argument you can specify how far backup rdup-simple looks back for previous backups. This
should be a number in the range 1..99. It defaults to 8 days.

rdup-simple will create the directory '~/.rdup' and will store its administrative files there. This
program does not need to be run with root permissions.

The last argument of rdup-simple is used as the destination; the following destinations are supported:

ssh:///user@host/directory Use 'ssh' as a protocol and 'user' as the remote user name. Store the backup
in 'directory' on the remote server 'host'. ssh://host/directory Use 'ssh' as a protocol and the current
username as the remote user name. Store the backup in 'directory' on the remote server 'host'.
file:///directory Use '/directory' to store the backup, 'file://' is optional. Note: there are 3 slashes
here. /directory Use '/directory' to store the backup. directory Use 'directory' in the current
directory for the backup. Making a backup

Making a backup is as simple as: rdup-simple ~ /adm /vol/backup/$HOSTNAME

~ and /adm are the directories to be backed up. Multiple directories or files are allowed on the command
line.

The backup will be stored in '/vol/backup/$HOSTNAME'.

For the backup a YYYYMM directory is created. In this directory specific day-dumps are placed. So the
first dump in October 2006, will created in 200610/01 and the second in 200610/02, etc.

You can use incremental dumps for ever, there is no need to do a full dump every once in a while.

Note that rdup-simple calls rdup-snap-link. This small utility will actually hardlink copy the previous
backup. The return value of rdup-snap-link will determine if a full or incremental dump will be
performed.

Remote backups

Note: for remote backups to work, the receiving machine must have rdup installed. Also note: there is no
colon between the hostname and the directory. Remote backup will create a pipeline of the form: rdup -c
DIR|FILE | ssh user@remotehost

rdup-shapshot -c -b backupdir

There is no provisioning for ssh so unless you have configured ssh to work without a passphrase you will
be asked to supply one. Also note that the PATH on the remote host should be set in such a way that all
the rdup-util scripts can be found.

OPTIONS

       -Pcommand
              Filter all output through command, which is called via `sh -c  command'.   Multiple  -P's  can  be
              used.
