DSI maintains security backups of AFS data users, e-mail’s accounts and databases from a specific period of time according to the availability of the disk space for each of these services.

Safety backup copies are executed on a daily basis therefore any safety copy that is requested by day it will be the backup from the previously night.

Despite the regular backups there are redundant disks that allows that even if there is a hardware or energetic failure the storage will be available, however this does not mean that several security copies exists for each day.
