"save a copy of the disk image"
When you have 500 servers and the average is 90gb that's a bit of a space
problem to copy multiple images of.....but VMWare can clone live.....you dont
have to switch off. Also for management purposes you want one way to back
everything up or you cant scale your backup system/capability.....
Snapshots are really like db logs its not something you leave for long because
of the disk space impacts and disk i/o impacts, you also cant live migrate VMs
while a snapshot is in place....I'd be surprised in LVM is more
effective/efficient than VMWare in this respect.....
If the backupdb.pl gives me a sane export into a flat file that is fine....many
dbs are done that way anyway, its very unlikely it will ever be needed.

I use KVM so I can't tell how good/bad VMWare fares in this regard, but
I didn't mean VM snapshot, sorry if I was unclear.
I literally meant you turn off the VM and save a copy of the disk image.
It may not be the most efficient way of course, and you can also simply
use normal backup software with disaster recovery functionality.
As long as it is able to properly deal with dirsrv database it should be

Everything but dirsrv databases is just files, that is correct.
