Use raid 1 mirroring... forget backups. THe chances of BOTH disks going out at
the SAME time are VERY few in chances.
thats what we use at www.pxmb.com
You could try TARing each maildir then TARing all the TARed maildirs into one
tar then gz or bz2 that huge tar and do the xfer. either way its gonna take
time.
Using the following Filesystem with these options, will help speed GREATLY..
reiserfs defaults,async,notail,noatime,nodiratime
look at the noatime,notail nodirtime... that right there gives you 40% speed
increase.. trust me I know. reiserfs is FAR superioer to ext3 when it comes to
small files...
good luck hope this helps.
