Diskeeper 14 (2010) has an option vcc defragmentation, what is the benefied using vcc defragmentation? What is the best defragmenting option , with or without vcc Thanks in Advanced
i'm sure the software includes a Help File or Online Help, hit the search and type VCC i know about VSS defrag which means that any file over 64mb won't be defragged in order to speed things up, but i'm not sure if VSS is the same as VCC.
-- EDIT Never mind, I just tested and the Vista commands don't do anything on W7; like the url said..... petty, since the commands on vista works really nice and defrag the disks ok........
actually VSS is for volume shadows copy stuff.. select the one that uses VSS defragmentation method and you're good to go. It prevents or keeps VSS at its minimal levels otherwise it will grow as you defrag..
the auto defrag (background defrag) is set to standard anyway rather than VSS, also you will have the benefit of intelliwrite which doesnt require VSS or use VSS
Currently I am using Dk2010 on XP; don't have 7 yet and I ditched Vista a while ago, but I had used DK2009 on Vista previously, and IIRC, when in auto defrag mode, if DK detects that VSS is active on a volume, it will automatically use the VSS mode for defrag. Logically, should be the same in w7 too. I believe DK's VSS defrag mode minimizes unnecessary file movement during defrag thus decreasing VSS activity and preventing purging of older snapshots. Yeah, intelliwrite is cool, fragmentation prevention means lesser defragging and therefore lesser messing around with VSS. PS: IIRC, this VSS mess occurs only when the cluster size is formatted at less than 16kB (weird, no?)..so for 4kB clusters (NTFS default), it's a problem, and most defraggers cannot find a way around it.
