Policy

There are at least three ways to make backups:

  • a) We give you a 5TB portable drive, you keep it and write to it. Please ask for one!
  • b) Use CrashPlan/rsync and/or DropBox/Sync/Box.com to create backups in the cloud.
  • c) We backup /nfs/home and some other disks, as follows:

Monthly backups

  • Cluster 2: nfs-home:/nfs/home/ (/nfs/home)
  • Cluster 2: nfs-soft:/nfs/soft (/nfs/soft)
  • Cluster 2: wiki
  • Cluster 2: selected sysadmin files (alpha, beta, config files)

Most disks are never backed up

Implicit backups

  • we backup ZINC20 and ZINC-22 to AWS and Wynton.
  • all software is in github/gitlab and is thus backed up continuously

Note

At time of writing, this policy is only implemented on Cluster 2.

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. Even better, just use your own USB drive!
