Backups of CCR systems are done for disaster recovery purposes only.  We can not guarantee backups complete in a certain time period (i.e. within 24 hours).   We make a best effort to back up all file changes daily but the more files that change on our systems on a given day, the longer that process takes. 

We highly recommend users backup their data offsite for additional protection.  Options include: UB Box or Microsoft OneDrive - provided by UBIT, your PC, other personal cloud options


What is backed up?

  • Home directories (/user/[username]) and project directories in /projects/academic on the core storage system are backed up to an offsite storage system by UB's Enterprise Infrastructure Services team.  See below for limits.  

  • Incremental backups occur daily

  • Backups are retained for 30 days


NO OTHER USER DATA IS BACKED UP! 

This includes:

-  data residing in /tmp or /scratch on ANY server or compute node

- the global scratch directories (i.e. /panasas/scratch)

- no backups of anything in the Lake Effect research cloud (more information)

- RPCI storage (/projects/rpci) is excluded from backups as part of the Cooperative Use Agreement and at the request of RPCI.

- Industry partner directories (/projects/industry) and are NOT backed up unless it is specified in the individual company's Cooperative Use Agreement to do so.


Limits of backup service

CCR is unable to backup user or project directories with more than 50 million files in them.  Any directory that reaches this limit will be excluded from the daily backups.  We will notify the faculty member/PI of the group before the directory is removed from backups.  However, it is the PI's responsibility to notify his/her group of this exclusion.  You can check how many files are in your directory using the iquota command:

iquota -u username

iquota -p /projects/academic/YourGroupName



Requesting a data restore:

  • Every effort will be made to retrieve requested data files from the backups, however we do not guarantee that the data can be recovered.  As stated above, we strongly recommend you keep copies of your important data on your personal machine, external disk, or cloud service.
  • To request a file or directory be restored from backup tape, please submit a ticket to CCR help providing the following information:  full file location to be restored, name of file/directory to be restored, date of last known time it was in this location.  Remember, if it's over 30 days, it will no longer be available for restore.
