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:


Backups are run as follows:
== Monthly backups ==
* Weekly starting Friday night: /nfs/home/
* Cluster 2: nfs-home:/nfs/home/ ('''/nfs/home''')
* Quarterly on the first day of the quarter: /nfs/db, /nfs/store
* Cluster 2: nfs-soft:/nfs/soft ('''/nfs/soft''')
* Never: /nfs/work, Laptops, Desktops
* Cluster 2: wiki
* No other user files are backed up, ever.
* Cluster 2: selected sysadmin files (alpha, beta, config files)
* 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. You may use CrashPlan or rsync for this.


We have four savepacks 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.

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

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. Better: use your own USB drive.
