As I sit here with Retrospect Remote on one side of my desk and ADSM on the
other, it looks bad for ADSM. Of course Retrospect was written on a Mac
for Macs to be used only by Macs but..... It's hard to make an argument
for ADSM. Admittedly I haven't set up a Mac client for ADSM yet but the
docs alone worry me...
1) 2Megs of disk space for ADSM (ouch) and about 120K for Restrospect.
2) Restrospect is a control panel. (This alone is a big plus, well at
least to the Mac-Hacks I'm dealing with) ADSM uses a separate
application. (Scheduler).
3) Retrospect has a small memory footprint when not active vs. the
apparent 1M of memory lost just to have the Scheduler active and it
apparently stays active all the time.
4) ADSM only supports client-polling for Macs (I don't quite understand
the reasoning behind this) rather than having the server control backup
initiations. (That's probably just a matter of personal preference
though).
5) Not earth-shatteringly important but, it would be really nice to turn
off the Mac when the backup is completed if you want, like Retrospect
does. It's a garnish type of effect but it really makes it easy
to explain to users, "See you don't have to worry about turning your
Mac off at night, we'll back it up and when we're done, we'll turn
it off for you." Users seem to get a big kick out of that one. :)
I'm not advocating Retrospect despite what it might sound like, I'd really
dislike to have a Mac sitting here doing backups. Something else to watch,
to monitor, to worry about changing tapes in etc... But the prospect of
telling some of the few hundred Macs out there I'm going to be backing up
that I'll need 2M of disk space and 1M of memory, is going to be scoffed
at by most anyone who doesn't have an at least 8/80 Mac. All those SE's
and early Mac II's with 4/40, and I know I've got a fair number out there
are not going to be amused with the requirements of ADSM. I'm going to
try out the Mac ADSM and give it a fair run, I may end up running some ADSM
Macs clients in-house and on a few servers but I'll probably end up running
Retrospect for users. I'd be real interested in future plans, updates, new
releases for the Mac client in a big way. Please keep up us informed if you
can and feel free to throw out ideas. I have a vested interest in ADSM already
and would like to see it to continue to expand.
