====== 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.**
