Data Backup Services

The Princeton Office of Information Technology (OIT) provides data backup service for all data stored on university-owned workstations and servers, and for OIT-operated storage services such as networked file storage, WebSpace, SharePoint, and the Exchange e-mail system. 

Backup service for university-owned desktop and laptop computers is provided by CrashPlan.  Data backed up by CrashPlan is encrypted and stored at a remote data center operated by Code42, the vendor of the CrashPlan product.

Backup service for servers and storage systems is provided by the Tivoli Storage Manager (TSM) software. TSM maintains copies of all active files both in an on-campus disk storage system and on magnetic tapes that are encrypted and stored in a secure off-campus location. These copies are maintained for 30 days after a file is deleted.

Backup service for files stored on OIT-operated networked file system is provided by a "snapshot" technology unique to that storage system. As a file changes, copies of the file (the snapshots) are saved at regular intervals and retained for 30 days.
