PCN Backups
All PCN-supported systems are backed up nightly.
- Both Unix systems and Windows systems can be backed up.
- Your home directory, and all filesystems residing on the RAID (this includes /class, /project, and /home) are backed up nightly.
- /project and /home directories stored on UNIX workstation local disks are backed up nightly.
- If you have a Windows system, either contact PCN to back up important data directly from your PC, or be sure to store your data on a backed up filesystem.
As of May, 2001, the following is the operational PCN backup system:
The first weekend of the month, a full (level 0) backup of the department is performed. These monthly backups will be kept for X years.
Every night, all filesystems are backed up, with a full backup occuring approximately every 6-7 days. These nightly incremental backups are kept for approximately 20-30 days.
What does this mean for my missing files?
This means that if your file was on disk for at least a day in the last month, it is most likely on tape somewhere.
Please remember that system backups are provided by PCN Maintained machines only.
Unsupported Machines
Although PCN cannot provide support to unsupported machines, use the following as basic information for configuring backups for your machine.
