Backup

Technical Service creates backups of all HOME-directories and of all users' systemmailboxes every day between 12 am and 3 am. This backup is saved on a RAID-system acquired especially for this purpose and is additionally secured to tapes once a week. 

If you have deleted files accidentally, you can retrieve them yourself via your backup which is saved on a disk system. 

You can find your backup under 

/backup/<login>/<date>/

The required date is the date the backup was created. 

 

One of the files in this directory is the file mailbox, in which the systemmailbox of the respective day is saved. Additionally, there is the directory home, in which the backup of HOME is saved.

User hugo then would get the following output: 

% ls -l /backup/hugo
