Client
Client
Client
1.Backup client to disk (File Library)
Backup server
2. Backup disk to tape (object copy)
Staging Area
Tape
3b. Direct restore from tape
3a. Fast restore from disk (if data still available)
Use cases
•Continuous backup of transaction log files (avoids tape drives being in start/stop mode)
•Backup of slow clients without multiplexing
•
•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.
