File Library

The HP OpenView Storage Data Protector Advanced Backup to Disk license (terabyte-based) enables the MSA1500 to be configured as a “file library,” so the initial backup from MSA1000 to MSA1500 takes place as a normal backup job with the file library being specified as the destination. The file library can be configured in much the same way as a tape device, with block size, segment count, disk buffers, and so on. It is important to realize that the backup file created on the MSA1500 is for all intent and purpose a tape image file. The benefit of this will be seen later when examining small file backup performance.

Using HP OpenView Storage Data Protector Advanced Backup to Disk, the migration of the backup on the MSA1500 to tape is executed by means of a “copy” style function. It can be interactive (manual) or scheduled to occur at a certain time or even directly after the initial backup to the MSA1500 has completed.

Two file libraries (“FileLibrary”, “FileLibrary10GB”) are created with different maximum file depot sizes (10, 50 GB).
