IRIDIA has a server where users can store their backups. It can be configured to automatically retrieve the data to backup from users' computers during the night.
Server Information
The server name is fallopius but it is registered temporally in the DNS as gibbs.ulb.ac.be and it is in IRIDIA. It will be moved to another building and its name will be changed into fallopius.ulb.ac.be. When? Hard to say...
You need a valid login to access the computer. Ask the system adminstrato to create one for you.
The server has globally 677 Gb available for backup. The HDs are configured according to RAID 5 architecture to assure more realiability and not to lose also your backups!
How to Access the Server
The server can be accessed only via SSH.
Quota
The server is the only machine in IRIDIA which sets quota for the users. Each user has a soft quota of 20 Gb, and a hard quota of 22 Gb. When the soft quota is exceeded, the user has 7 days to reduce its occupied space. After 7 days, or in any case if the hard quota is exceeded, the user account is blocked and the only thing he can do is to remove files.
Manual Backup
Using ssh and scp, each user can copy his data on fallopius. Other programs that might be used are duplicity and rdiff-backup.
Automatic Backup
The server can be configure to automatically retrieve the data to backup from users' computers. This procedure is described more in detail in the README file that each user finds in his home directory at the first login. Please read that file first, and if you have more doubt ask the system administrator.
Once the setup of an account is completed, the server proceeds to automatic retrieval of the data each evening at 22:00 on odd days (the 1st, 3rd, 5th, and so on). At the end of the procedure, an email is sent to the owner of the accunt with the result of the backup.
