Sysadmin:Backup

In Progress: Tapes

• Changing a magazine
• Doing a full monthly backup
• Amanda restore
• Tape retention policy
• Cleaning the autoloader
• Changing a tape
• Restoring without AMANDA

Note: You may need to powercycle the server if the changer is not responding. This may involve physically removing power if an instant reboot doesn't fix it.

Current Setup

Rsnapshot takes copies of files off Quark (by ssh), 41's internal IP (by SSH), hopper (nfs), and bobsced0 (nfs). The current rsnapshot schedule is as follows. Update: 6/19/09 - We switched to using ssh with hopper and bobsced0 because we were seeing odd behavior with the cluster mounts after moving to 42.

0  0,7,16,20    * * *       root    /usr/bin/rsnapshot hourly
0  3            * * *       root    /usr/bin/rsnapshot daily
0  6            * * 1       root    /usr/bin/rsnapshot weekly
0  2            1 * *       root    /usr/bin/rsnapshot monthly

This translates to a week looking roughly like this. Keep in mind that each backup takes approximately an hour and a half to complete (not shown below for simplicity). In addition, a backup is run the first of every month at 2:00 a.m.
