Backup and Restore

Backups

We backup all home and work file systems nightly on a backup server located at ITA. We also keep a up to 30 days history of all files based on nightly snapshots.

Restore

If you need to restore some files from /home/Tux or /work/Tux* , you can do

 

sftp backup

connecting to our backup server. See "man sftp" how to use it. After login you are in path of your latest backup.

 

/backup/ARI/home/Tux/username

Consider, that there are all those older backups in the the directory tree in parallel to the latest. E.g.:

 

/backup/ARI/home/Tux/
/backup/ARI/home/Tux_2016-03-04~01:46:00/
 ... 
/backup/ARI/work/Tux2 /work/Tux2_2016-02-22~01:39:00/ 
...

So it might be wise to start directly at a sub path instead at your home. E.g.

 

sftp backup:/backup/ARI/work

sftp is fine if you only need a few files restored. But if you need a tree of directories and subdirectories recovery, please ask our Admins.

Disaster Recovery

In case of a loss of a whole file system or disk array, the backup file server can be configured as a NAS sever. So we can offer a backup file system as a replacement of the original service. This is the big advantage of a disk backup versus a tape backup which we had before the year 2010.
