I am seeing incredible fragmentation on the drive we use to store our BackupToDisk files. I'm posting more details below, but if you are using B2D, could you please check the fragmentation level for me and let me know if you are also having this problem.
We have a 570Gb NAS device used as the main target for all of our backups. This device has been in use for approximately 6 months and is used almost exclusively for B2D backups.
After numerous problems with BackupExec, I happened to run a defrag analysis on this device, with the following results: http://www.averysilly.com/Defrag%20report.jpg.
Even after deleting 350Gb of B2D files, we are still getting 99% fragmentation reported with files scattered across the entire disk, and with a 1Gb b2d file in as many as 40,000 fragments.
I am still speaking with Veritas, we've no clear idea what caused this, but on at least one occasion I have set BackupExec to allow concurrent operations to this B2D device, and we suspect this may be the cause of this fragmentation.
We are defragmenting this device today to see if it fixes our problems, but I would be very interested to know if anyone else is seeing similar effects on their B2D devices?
