Overall System Status:
Regular backups are made of the public UNIX systems of Academic Computing, which include the AFS file servers and all of the central systems.
These backups are designed to protect against hardware failures and short-term emergencies only. They are not permanent archives. If you need to restore lost files, you should seek help promptly while the backups are still available. Backup tapes are overwritten once they expire. The backup scheme used for the AFS file servers and local disks are slightly different. Most user files are stored in AFS.
All files, whether local to a single computer or in the AFS system (visible to all of the computers), are backed up using the following general scheme:
Files can be restored to the state they were in at any daily backup for the past 14 days, the previous weekly backup, and to any monthly backup from the past year. Files of users who have left and been removed from the system can be recovered for up to one year.
ALL files in AFS, including user home directories and RStor data volumes, have an additional daily snapshot facility.
Substitute your AFS account name for 'myusername', and the first letter of your name for '/m/'
The exact time of the backups may be important to know when determining which files to restore. This may change; consult with the system administrators for the latest information. As of March 2012:
