I agree with the graceful shutdown of the server before the snapshot.
Not only does it allow for a more reliable snapshot, but it also
results in a much smaller set of snapshot files since it doesn't have
to take a snapshot file equal to the size of all of your mapped
physical memory for your guest os. Probably saves you 2GB of space per
snapshot on average (of course folks memory requirements will vary).
Cheers,

I do the same thing, only I will do a graceful shutdown of the

squirrelly things going on until I started doing it that way.

method??
Use snapshots.
What the snapshot does is essentially mark where your server is
currently, even capturing the memory at that moment. So after a
snapshot is made, changes to the server are all logged. So what i
typically do is install CUCM, snapshot after i verified the install
and made sure it was working. Then, I will in the future as I lab
off workbook one, snapshot after each lab session.
So for instance, my snapshots would look like,
Initial Install --> Lab1A --> Lab1B --> etc, etc
So, if say you screw up during a lab or for whatever reason you want
to revert back to before you started, you restore the snapshot, and
continue on from the *exact* place you took it [the snapshot].

Have you tried using BARS or DRS? Again not sure on your CCM version.

i am so sick and tired with this... the main problem for which i
thot vmware had a solution is still stinking me... how do i do a
proper backup and restore?? i mena i have pub and sub... my pub had
a db connectivity error(due to an abrupt power failure)...sub was
fine... i had already cloned all my vmwares into another backupdir..
so i copied the pub clone and thot i was done... first of all.. the
db wipes clean.. yeah..yeah..obviously.. but now i cant even find
the sub as an available node for my cucm-group.. however all sub
configurations can be changed and is reflected on the pub gui
itself... yes i have cross checked the serviceablity for both nodes
and thats fine....
my backup strat is pretty boring i know.. i still havent figured
what the snapshots do... if anyone can suggest a better way to
backup my servers it would be great.. my head is spinning on the
thoughts of a cucm reinstall from dvd... even a quadcore q9550 with
8gb ram has its limits on sluggish algorithms(redhat-cisco-
installation-scripts) u see ;( .
