Backup Solution too slow, need help

[AV1611]

I have about 9 gigs of data that I need to get across a T1 every night onto an external USB hard drive on a Server on the other side of this T1. Its a point to point T1.

It is taking about 16 hours and I need it done in about 5. I don't have to resend the whole 9gigs if I can figure out how to do an incremental or some other kind of backup that just adds the changed or new files to the backup.

I used Microsofts back and backed up to a file on that External USB.

What other choices or options do I have? And how can I set something up to run every night that will just send the changed data over there for me?

Thanks in advance, AV

Try Veritas Volume Replicator .... $$$$$

try Microsoft's Robocopy, it is part of the resource kit

Do you have a link to any information on how to use Robocopy??

Thanks, AV

If i were you i would use Linux to do this. Setup 2 servers, one on each side with a linux distro and use rsync. I use rsync and its a good app to run backups with. It does file transfers at the byte level so when you run the backup it only transfers the actual byte changes in the file and not the whole thing. This would help your speed greatly. It would probably reduce your backup time to about 3 hours, maybe even less. I run a backup over a vpn, using a dsl line. The backups that I run total about 200gigs, but after the first time that rsync runs, backups would be much faster. Once it has the main images of your directories it will only transfer the changes on a day to day basis. You could even keep incremental backups on the files by using tar to compresso the changes. All of this may be good for you to look at, i was having the same backup issues before i started to use rsync.

Seeya!

If a fast and reliable backup is that important to you, back up locally. You can get a tape drive or a hard drive for the system. Hard drives are dirt cheap, and maybe you could buy a used 12 GB if that's all you need. As you are seeing, a lot more can go wrong with a network backup.

I can't afford to do two linux servers at the moment. Also a comment to bfks3230, I have a tape on each site, the reason I am doing this backup is so I don't have to take a tape home every night from each site, I can just have an offsite backup for fires.

Thanks, AV

How about zipping up all changed files every night? Copy the zip file across the T1 and then extract the zipped files.

Availl will automatcally do the delta (difference) at the byte level and send it. figure about 1 hour per GB of difference.

AV1611,

You could get a fireproof safe and put the tapes in there.
