Commvault Galaxy?

Is anyone using it on Windows to backup a number (approx 20) of file and
application servers on a gig switched network, to an LTO library?

Any thoughts on it?

We currently use Arcserve, we're replacing a bunch of kit and Dell now
offer Galaxy, we had their rep in to see us and it looks like a "proper"
enterprise product rather than the likes of Arcserve/Netbackup which look
like standalone products that they've tried to scale upwards.

I use CommVault Galaxy in my environment.
I have a HP MSL6060 library, with the fibre option.
I have 8 Large Linux fileservers that back up to disk and tape using
fibre channel directly.

It is the best system I have used. Hands down.

It is a capable, and complex system. Training classes are essential.

It is very configurable, and everything can be automated using policies
and schedules.

It does "synthetic full" backups, which consolidates your incremental
backups into a 'full' backup without re-copying data from the client.
Very useful, and fast.

If you can, a fibre channel solution will offload the network by not
using it for data transport.
Sending data over the network will still work well, tho.

My only concern in my environment is that the "scan" phase takes a
while. I have many 2TB filesystems with large number of small files, and
'tagging' them for backup is slow and resource-intensive, before the
actual backup starts.
If you have smaller than 300GB filesystems, I wouldn't worry.

It is also unforgiving of errors in your DNS setup. It needs to work
flawlessly, reverse lookups also.

They also have archiving solutions for windows/exchange and products to
migrate seldom-accessed files from disk to tape transparently.

Support is good.

I would recommend CommVault. And advise against overstretching solutions
like BackupExec or ArcServe.

Thanks Frank, I appreciate it's the only reply (what a dead group!) but
it's still reassuring to get an opinion from someone who uses it.

That was the impression I got when we had the rep in, he had it installed
on his laptop and it looks like it can do _a lot_ but having used Arcserve
for so long it's sometimes tricky to view products with no preconceptions.

Hmm.. what we will hopefully be having is a large central fileserver
consisting an HP MSA20 SCSI attached, SATA drive enclosure with approx 3tb
storage, attached to a HP server of some sort which the tape library will
also connect to.

The array will hold around 700gb to start with and will obviously grow as
we try to lose physical fileservers.

The tape library is a Dell Powervault 128 twin drive LTO library.

That's all setup prefectly.. I'll take the credit for that :-)

Arcserve 2000 is what we use right now. Frankly it's horrible.

At present we tend to do fairly normal GFS rotations, my boss deals
with it andknows the specifics, but basically daily tapes stay in the
library and get overwritten each day of the week on a differential backup,
and on a Friday either a weekly or monthly full backup takes place -
standard thing for something like Galaxy I assume?

Thanks for taking the time to reply, it's appreciated.

All of that is policy-based.
You create a storage policy. The "primary" copy can be either tape or
disk. Data will be sent here first.
The primary copy can have retentions associated with it that says "keep
fulls for 3 months, and incrementals for 1 month". Galaxy will keep
track of that. You can have secondary copies made for offsite storage,
with infinite retention. You can specify which runs will be copied to
offsite, fulls, full+incrementals, etc.
Once policies are set up they will basically do all the media management
and recycle tapes for you.

You can even have fulls and incremental backups from the same FS sent to
different storage policies, if you want.

It's complicated, but some training and experimenting should clear it up.

No problem.
The group IS a little dead, tho
