rdup-restore(8) - Linux man page

Name

rdup-restore - restore a filesystem from a specific directory

Synopsis

rdup-restore [ OPTIONS ] -b TO_DIR FROM_DIR [ FROM_DIR ... ]

Description

rdup-restore is a frontend to 'rdup-cp' and 'rdup'. It will restore everything under FROM_DIRs to TO_DIR.

Note; if you still backup with 'rdup-dump' you can only restore to the latest state of your backup. With 'rdup-snapshot' you can also restore to any previous state, see rdup-snapshot(8).

Restoring from a backup is as simple as: rdup-restore -b /tmp/home /vol/backup/elektron/200604/home

Note: The restored files "inherit" the '/vol/backup/elektron/200604' prefix. So the restored files are found in the directory: '/tmp/home/vol/backup/elektron/200604/home'.

Options

-S

Restore a rdup-snapshot backup. This is a hardlinked backup, so one can also restore these with 'cp'. Consider this a convient function.

-D

Restore a rdup-dump backup. Due to the way this backup is made, you can only restore to the latest version of your backup. -D is the default for rdup-restore.

-b TO_DIR

This option is mandatory. It specifies the directory where the backup should be restored in.

-c user@remotehost

Pull a backup from a remote host. This will create a pipeline of the form:

ssh user@remotehost rdup -c /dev/null FROM_DIR | rdup-mirror -c TO_DIR

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-utils can be found.

-k keyfile

Decrypt the files while restoring with keyfile. This option inserts rdup-crypt -d keyfile in the pipeline. If both -z and -k are given they are performed in the order they are given.

-z

Decompress the files while restoring. This option inserts rdup-gzip -d in the pipeline. If both -z and -k are given a file is first decrypted and then unzipped. This is ofcourse the opposite of what rdup-dump does.

-a

Enable extended attributes. Rad the uid/gid to the extended user attributes r_uid and r_gid.

-v

Echo the files processed to standard error.

-h

Show a short help message.

-V

Show the version.
