If you feel your backups runs too long there can be many reasons for that, slow tape drives, a saturated network, etc. Sometimes the clients to backup does not deliver the data as required, maybe the disks are too slow. A good way to to test the performance of a server is using a null device. If you need faster results and no configuration within Data Protector you can test the server performance using the binary vbda<\/code>. VBDA – Volume Backup Disk Agent – normally reads the data and sent it to the media agent, however you can use VBDA to test the speed of your servers’s disks. With some parameterts a backup is simulated and as a result you get the read performance which would be achieved during the backup.<\/p>\n

Example (Windows, Linux\/Unix may differ):<\/u>
\"c:\\program files\\omniback\\bin\\vbda.exe\" -vol \/C -trees \"\/Windows\/System32\" -out nul -profile<\/code>. The command starts a backup for volume C:<\/code>, backups the tree \/Windows\/system32<\/code> (be careful with the separator). The backup will be done to a null device and will not require a configuration in DP beforehand. In addition statistical information is collected with -profile<\/code>.<\/p>\n

See the result as example:<\/p>\n
