ACCRE provides tape backup services to Vanderbilt departments and laboratories regardless of whether they also use the cluster. This is an additional service separate from the backup of home and scratch space on the cluster (see the cluster policy on disk quotas and backups).

The True incremental Backup System (TiBS) is used to backup data for these departments and labs. Currently, an Overland Storage NEO8000 Tape Library is used for the backup of data located remotely. An important advantage of TiBS is that it minimizes the time and network resources required for backups, even full backups. After an initial full backup, TiBS performs incremental backups from the client. To create subsequent full backups, an incremental backup is taken from the client. Then, on the server side, all incrementals since the last full backup are merged into the previous full backup to create a new full backup. This takes the load off the client machine and network. The integrity of the previous full backup is also verified by this process. TiBS support is available for all current operating systems. Please contact ACCRE Administration for more details.

The terms of this service are covered by the attached Service Level Agreement.

The charges for this service are:

• $750 per year for up to 1 TB compressed data (which includes 1 free one-hour restore per 1 TB per year)
• Please renew the SLA for full pricing information. The backup schedules that are available are listed on the SLA Attachment 1.
