RE: [Veritas-bu] Windows File Fragmentation
Title: Message Diskeeper may be worth a look, HOWEVER, I haev had MAJOR issues with this product trying to run after a backup as it appeared to clear the archive attribute. Fragmentation is an issue, so where poss, try to defrag when backups are not required or may JUST before a FULL Backup (that way keeps the archive bit !)

RE: [Veritas-bu] Windows File Fragmentation
The server i'm having high fragmentation is a Lotus Domino server. I talked to lotus and they do not recommend defragmentation while domino is running. I'd probably need a 4 to 8hr outage window to defrag the drive. Today i had a small outage window on the server so i upgraded the Raid Controller Firmware, Server Bios and Upgraded the broadcom GB drivers. For the time being the backup server isn't having slow backup performance since the updates. Yeah! So i have some breathing room until i can get a long outage window. In the past, slow performance has shown up after two weeks. At anyrate, i still need to defrag the drive.

RE: [Veritas-bu] Windows File Fragmentation
Yes. Though I would not have believed it at this time. 12 Disk RAID set on SAN. We noticed a large decrease in our backup window after defragging our drives.
