Policy
Backups are run as follows:
- Weekly starting Friday night: /nfs/home/
- Quarterly on the first day of the quarter: /nfs/db, /nfs/store
- Never: /nfs/work, Laptops, Desktops
- No other user files are backed up, ever, unless by special request and agreed by email exchange.
- You are encouraged to use a USB drive on your desktop or laptop for supplemental backups of key files.
- You may copy files from laptop, desktop, instrument machines or elsewhere to your /nfs/home or /nfs/store directories for backup. You may use CrashPlan or rsync for this.
We have four savepacks (sets of tapes, in a suitcase) that we rotate for /nfs/home. We set aside one of these savepacks quarterly, on the first backup of the quarter, as an offsite backup. Thus at any time there is a weekly backup made starting Friday night for the last four weeks, and a quarterly backup for the last four quarters.
Note
At time of writing, this policy is only implemented on Cluster 2. Cluster 0 starts June 1, 2014 (with caveats).
Restore
To have files restored from backup, please write to the sysadmins, stating file/directory name, the approximate time of when it was created in the form you want restored and when that copy was deleted or damaged.
