Magnetic tape and similar storage media offer an inexpensive and portable form of data protection that is particularly useful for long-term storage.

In DPM, you can back up data from a computer directly to tape. You can also back up data from the disk-based replica. The advantage of creating your long-term backup on tape from the disk-based replica is that the backup operation can occur at any time with no impact on the computer being protected.

Additionally, a thorough disaster recovery plan will include offsite storage of critical information; you want to be able to recover your organization's data, in a situation where your facility might be damaged or destroyed. Tape is a popular medium for offsite storage.
