Backup tapes out of space - strategical problem!!

We have one server with pretty much everything on it (DNS, AD, Exchange, etc.) running Win 2003 SBS.
To back up we have Symantec Backup exec system recovery that backs up on a remote hard drive on the network and Symantec backup Exec that backs up on 2 tapes. Each tape is 80Gb uncompressed.
We can possibly squeeze in another 10Gb max on both tapes together.
The problem is that we are buying another server (win 2008 std) to run as terminal server. It will eventually need to be backed up as well.
What would be the cheapest way to expand the back up strategy?
I am thinking of these options -
1. Leave the tapes as they are and back up the new server only with Symantec System recovery to the same remote hard drive.
2. Buy another 80Gb tape drive and put it in the new server.
(Both of these solutions would still mean that once the 2 tapes on SBS 2003 server are full, we'll need to invest in a new tape drive.)
3. Buy a 200Gb tape drive and put it in the old SBS server replacing the 2 80Gb tapes. Put one of the old 80Gb tapes in the new server.
This solution would be obviously the most expensive.

Any suggestions or completely different solutions are welcome!!

It depends how much space you will be using on the TS server.

If you plan it well, I don't think it will require much, so you may be able to get away with the minimum of putting the backup on the remote hard drive.

I would also look into reducing your backup load via archiving if at all possible.

Anything that has not changed in 90 days gets removed from the server and put somewhere else ( even an external drive can be used after a tape backup has been done and archived )

I hope this helps !

We are already achiving as much as we can on a separate tape. But the data amount still increases.

The disadvantage of backing up only to a remote hard drive is that in case of any (natural) disaster we won't have the any backup whereas I always take the tapes home.

I was also planning on migrating the domain controller role to the new server - which mean it would need to be properly backed up and allow granular restore. In case for example a user account has been deleted. Only Backup Exec can do that on a tape. System recovery won't help here.
Unless there is a way to run a symantec backup exec remote agent on the new server and back it up back to the tape on the old server. Then again there is not enough space on the tapes. :S
If your backup needs are growing, then it would seem time to get another tape drive or alternative ( external eSATA and disk to DIsk for most data and then Disk to tape during the day )

I hope this helps !

I would buy a new tape and give yourself plenty of headroom.

We have recently moved from SDLT (160/320) to LTO3 which is 400/800) so expect to get about 600Gb on each tape. We would have gone to LTO4 but the drives provided by Dell only run on SAS and we have SCSI. LTO gives you more space and faster read/write.

LTO are all backwards compatible (see chart below) so you would also be future proofing.

I think that LTO is definitely the way to go.  LTO is far more robust and reliable than SDLT.  For the amount of data that you need to backup, I would say that LTO-3 or two LTO-2 drives (one for each server) would be your best bet.

One of the issues you may run into in backing up both servers to one drive is that an LTO-3 drives run at ~75MB/sec, which is far more than even Gigabit ethernet can handle.  We have discovered that the sustained transfer required by even LTO-2's (~30MB/sec) is too much to back up over the network.

There are three possibilities.  One, if the servers have shared storage (SAN), you should be able to have Backup Exec send both partitions directly to tape.  Two, if you have enough storage on one of the servers, you can backup one server onto the other and then to tape.  Or, three, set up a dedicated backup server to receive backup from the other servers over the network and then write them to tape.

Thanks for you advice. I just wanted to ask about this product - would it be able to replace the tape drives
seems like a inexpensive solution..
You should be able to pick up used/refurbished LTO-2 drives for about $500/ea, or about 2X the cost of an RD1000 drive.  However, new/sealed LTO-2 media (200/400GB) is in the $50 range, versus $239 for a 160/320GB RD1000 Removable Hard Drive.  If you're doing daily backups, you'll see a significant savings with LTO-2.  The data transfer rates are comparable (~30MB/sec).

LTO-3 drives are much faster (~75MB/sec) and the media is not much more than LTO-2 media.  The drives are much more expensive, though.

Tapes are more resilient than hard drives, but you still don't want to drop them.

All prices are educated guesses (or from Dell US) and in US dollars.

You have to factor in the cost of having enough of those disks that you can take them off site and rotate them to ensure you always have data stored safely off site. No point in having one nice backup on site if the building goes up in flames.

I would also be very wary of carting one of them about to and from home. As LTO Moe says, tape is much more resilient and is what we use.
