Quick backups with ssh and gzip

As a SysAdmin I sometimes need to make quick backups of a filesystem to a remote machine. Unix provides easy and quick ways to do this task.

The following command line uses dd – destroy disk command ;-) – to copy the content of /dev/hda11 and send the output to gzip and copy the resulting compressed file to the remote machine through ssh. The syntax is as follows:

dd if=/dev/hda11 | gzip | ssh user@remote_server dd of=/dest/path/hda11.gz

Note that /dev/hda11 should not be mounted (not accessed while backing up).

To restore the backed up filesystem do the following:

dd if=hda11.gz | gzip -d | ssh user@remote_host dd of=/dev/hda11

And your done! Quick and dirty backup for you.
