Hello List. I'm worried because my migration scheme is giving problems. My migration plan was use rsync for transfer all user's mailbox, but it don't work because my directory tree is very big. I have around 50K maildir directory (110 GB approx). I checked the rsync documentation and I note that it have memory problems with big directory tree (It use a lot of memory and it does shutdown my server). I need transfer all the maildirs without turn off the mail service or in any case, the time off of service should be short, for that reason I did think use rsync, because it could make incremental copy.
Please, somebody know others alternative to rsync? Bye
