Personal and Project Data
maintains highly available file server with NFS and SMB/CIFS connectivity.
This file server is integrated with the rest of our services.
Backup and Restore
All files are backed up to tape
daily. We also have daily snapshots
of all files.
If you need to recover files you can first check on the snapshot server
and copy the data over yourself. For a restore from tape please contact our service desk

Access and security
Groups that use the iiStore
cluster for file services need to be aware of the customization options and configuration of their storage.
The number of filesystems and their size depends on the amount and type of data:
- The maximum supported size of a file system is about 1TB. If there is more data it needs to be distributed in a meaningful fashion over several filesystems. Larger filesystems are technically possible but are difficult to handle for backup and recovery operations (e.g. fsck).
- Groups that have project directories and want to control data usage using disk quota are advised to put home directories and project data on separate filesystems.
For file systems on iiStore
an additional nagging
quota may be active. This quota is not enforced technically but you (and your ITC
) are informed by mail when your nagging
disk quota on a particular file system is exceeded. For more information see here
disk quota limits can be viewed in your user account details for your group here

The data of a particular group is accessed using a dedicated IP with one or more host names. The default is
