Backup of departemental servers
The departemental machines administered by the systeemgroep use Back-up as a service: TSM from the service catalog of the central ICTS.- User's home directories
:
A daily backup is taken and the backups are kept for at least 1 month, at most 3 months.
- Servers (e.g. mail, web, ...):
A daily backup is taken and the backups are stored for at least 1 month, at most 3 months.
- directories with name NoCsBack (case is important) are not backupped (including subdirs and files).
- backups are taken during the night. The exact time depends on the backup service of central ICTS.

Details for home directories:
Backup of your own machine
To make backup of your own (self administered) machine there are a number of possibilities.-
The LUDIT/ICTS backup system (local documentation) for self-administered machines and/or machines that are not day and night connected to departmental networks; login with your departmental account and password.
Beware this involves yearly costs. To include your machine contact helpdesk@cs.kuleuven.be .

A (possibly automatic) copy of your files to a machine that is included in the departmental backup system:
-
generally not suited for a complete backup of your entire system, but only for specific directories (e.g. My Documents or /home ... )
-
on Microsoft Windows you can have automatic synchronization (so backup
without manual intervention except for initial configuration) to a Samba server (look under Synchronizing
Directories)
This is no real backup solution in the strict sense because every operation is synchronized directly (unless you are working off-line) to the remote location so you cannot recover previous versions. But if the directory you synchronize to is included in a real backup solution, you can of course recover older versions there.
- cs-rsync-backup:
our own wrapper around rsync written in bash
Copy/mirror your laptop home directory to your departmental home directory ... because your departmental home directory is (most probably ;-) included in the departmental backup schema, this is (almost) just as good as a direct backup.
Primarily intended to be used on system-group-administered laptops, but might be a good starting point for others as well. - csbackup:
a wrapper around rsync written in bash to sync files to a file server
with some nice extra goodies to make life easier
Copy/mirror directories to a remote system ... so no (older) versions of files and directories, unless the remote system is being backuped.
Contributed by Yves Frederix ... definitely works on Linux, probably also on MacOS.

Automated Snapshot-Style Backups with Linux and Rsync
A true backup solution with different versions of backuped files and directories yet as little disk-space needed as possible ... relies on the functionality of hard links.
- other solutions based on SMB/CIFS copy to Samba server or
rsync or unison or ... can probably be found using an Internet Search
Engine
Only as good as your discipline to configure it and (let it) run it as often as needed ... good to know:
- rsync and unison are able to use ssh to communicate with the remote server to copy to
- the departmental ssh servers are accessible from anywhere in the world
- the departmental ssh servers have access to your home directory
- so in principle this gives you enough building blocks
to copy from your local machine to your departmental home directory
from anywhere in the world:
rsync -e ssh -aHv --delete /your/local/directory ssh.cs.kuleuven.be:/home/you/BACKUP
- whatever solution you choose, remember to test it from time to time, to see whether it still works as you expect (otherwise you will find it to have missed some important file or directory just after you have deleted it ;-)
