You'll almost certainly end up with an unusable copy if you let the VM run while copying - unless you can isolate changes with a snapshot. I'm not a filesystem expert, but the filesystem type might make a big difference in how much rsync has to copy. I believe some filesystems cluster the inodes and some distribute them across the disk. The ctimes will change in a lot of the inodes each day as the link counts change, and if the inode data is distributed, rsync may find many more locations with changes. > For the 2GB chunks idea it'll take quiet a while to migrate the 540GB > vmdk to 2GB chunks. Oh, and I think ESX does not support this type... I think vmware server can do it, but I'm having trouble finding a spot with enough space since I took the full amount on the physical drives for what I want to mirror. -- Les Mikesell lesmikes...@gmail.com ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
