If you're considering replacing your tape library, now is the time to
consider a combo disk/tape solution. Depending on the amount of data
and your config, you could have a system that allows you to store all
onsite backups on disk and only offsite backups on tape -- for
approximately the same cost as a tape-only solution.
I just delivered the results of a backup assessment at a new client
today, and they were the first client I've seen that had 100% success
rate on all their backups without professional assistance. Their
secret? ALL backups go to VTL before going to tape. (They backup about
40 TB a day.) Come on in, the water's warm! ;)
It may sound self serving for me to say this, but the complexity of the
new choices and the speed with which the market is changing right now
makes getting advice from an independent expert (who doesn't sell any
hardware or software) extremely important. If they're any good, then
they should offset the cost of their services with savings and/or
significant increase in backup/recovery capabilities. If that's
interesting to you, feel free to give me a buzz. ;)

Subject: [Networker] Recommendations for new tape library?
Hi,
Just looking for some feedback here. We need to procure a new tape
library soon. We have an older Storagetek L80 with
8 LTO-3 drives (79 data slots). This has worked nicely, but I don't see
us upgrading it to LTO-4 drives, although it might be possible.
Storagetek is still supporting it, but it is getting old, and we'd like
to get a new library to take us further down the road. We will remain
with LTO technology, so we plan to move to LTO-4. I don't anticipate
moving any of the existing LTO-3 drives to the new library
via drive conversion kits (I know this can be done when working with the
same library manufacturer). We will run the L80 in parallel
for a while, however. We're running NW 7.2.2 on a Solaris server with
two RH Linux snodes, but we will move to 7.3.x at some point soon.
Not sure if 7.2.2 even supports LTO-4.
Desired library options:
o Rack mountable
o At least four LTO-4 drives with room to expand up to 8.
o Fiber channel might be preferred but would be nice if it could do SCSI
if need be.
o Will be connecting to RH Linux storage node server
o Ability to move tapes around using GUI panel would be nice
o A CAP door with 1-5 slots is preferred
I would prefer to avoid stackable type units. I pretty much want it all
in one. We had a bad experience with one stackable style library wherein
the company stopped manufacturing the unit so we couldn't add more
drives even though they still support it for maintenance.
One thing I don't like about our L80 is that you can't move tapes around
in the library using the GUI panel on the library. Instead, you have to
use the OS.
It's really more of an annoyance than anything else. Otherwise, the L80
has been great.
Not sure how many slots we would need, but given that LTO-4 is double
the capacity of LTO-3, I suppose we could get by with 40 slots, but
might
be nice to have more.
I know we will require another Authochanger license, and that's gonna
run some money, too!, not to mention the media, but at least we'll be
able
to write to any new LTO-3 tapes that we still have using the LTO-4
drives.
I'm tempted to stick with Storagetek since we've had a very good
experience with them, but I am open to suggestions.
If anyone is using a newer STK library, I would be curious to learn what
you're using.
Thanks, and I would appreciate any advice or suggestions.
George
