3a. Fast restore from
disk (if data still
available)
Staging Area
1. Backup client to disk
(File Library)
2. Backup disk to
tape (object copy)
3b. Direct restore from
tape
Use cases
• Continuous backup of transaction log files (avoids tape drives being in start/stop mode)
• Backup of slow clients without multiplexing
• Tape-less branch office backup
• Faster small file backup
• Resource sharing
On the other hand, database backups are typically not first candidates for a D2D2T backup solution.
The direct backup of large database files to tape can usually be done very efficiently, utilizing the full
performance of the tape drive.
