Backup help for small LAN

By M3ckon ·
Can someone help (please?)

I have an 80 users LAN that I've just took over and the backup is abismal. They're using an offsite program for key files, but that's all they have.

I was going to implement an SDLT drive imediatley and then look at a full SAN solution.

I was just wanting some advice really as unfortunatley i dont have a massive budjet, but felt that an initial tape backup was a very good idea

Can anyone provide me with their thougths/comments please?

What are you backing up?

by jdmercha In reply to Backup help for small LAN

How much data do you need to backup? How many servers? Are you backing up the PC's as well? What type of network? MS? Novell? Linux? What type of LAN? 10MB? 100MB? 2GB?

Backup Content

by M3ckon In reply to What are you backing up?

Thanks for getting back to me

It's on a 100mbs network and it's a microsoft windows network.

I've looked and at present there is 12 gig of files and 5 gig of databases. I was going to consider an sdlt drive.

I can probably justify anything under $6,000 but the less I spend the better. I just need what ever is backed up to be able to be moved off site.

Thanks M3ckon

My choice

by jdmercha In reply to Backup Content

Of course saving money is always a good thing, and there are many good solution proposed here.

But if it were me, with a $6,000 budget I would seriouly consider a complete server solution. I took a quick look at Dell's website and it appears that for around $4,000 you can get a server with a built-in 36/73GB DAT. Including tapes and backup software.

JDMercha asks good questions..answer them first so we can help..

by TomSal In reply to Backup help for small LAN

JDmercha is right...we'd need more information. If you answer his/her questions, then we can collectively offer the best advice possible.

I would like to know even if just a ballpark figure...the kind of budget you'd have for a backup solution too.

My LAN backup solution

by jdclyde In reply to Backup help for small LAN

I took an IBM x205 server, got a promise IDE controller card and threw four 200 gig drives in it.

800 Gig total.

I then have a tape drive connected to that one server.

The individual servers and key PC's backup to this server automaticly, and then the tape is run.

Soon will be looking to add a DVD writer to the backup server. Anyone using a DVD as part of their backup solution now?

I'm a big advocate of DVD-RW backups

by stress junkie In reply to My LAN backup solution

I'm glad that you mention using DVD-RW media for backups. I think that it is a great idea. It has many advantages including economic. When I think of paying between $1,000 to $10,000 for an SDLT tape drive and up to $100 per tape, depending on density, the DVD-RW drives and media look like a good option. Sure they only handle a fraction of the capacity of SDLT but they cost much less so the cost evens out. The lower cost of the DVD-RW drive is pure cost savings.

Plus, in the U.S. the Sarbanes-Oxley Act requires that some backups be made on write once media. Magnetic tape only emulates this. DVD-R is actually true write once media.

You can further save costs by putting a couple of DVD-RW drives into an old pc and using Linux with Samba to backup Windows systems over the network via disk file shares on the clients. Admittedly, if you aren't familiar with Unix/Linux then the details of implementing this simple solution would still require a bit of effort learning Linux.

Nevertheless I'm a big believer in using DVD-R and DVD-RW instead of magnetic tapes. A word of caution though. I've heard that the cheap writeable CDs and DVDs will delaminate after a few years. The more expensive ones should last decades either in use or in archive storage.

Failure rate

by jdmercha In reply to I'm a big advocate of DVD ...

Is the failure rate on a DVD-R better than a CD-R?

I've seen a typical failure rate on CD-R's to be about 20%.

20% ?

by jdclyde In reply to Failure rate

Sounds like you need to do one or more of the following.

Buy name brand CD's.
Buy a better writter.
Write at a slower speed.
Run a CD Drive cleaner through your system.

If I scrap one in ten I am pissed off. How can you put up with one out of five?

Name Brand

by jdmercha In reply to 20% ?

Yes 20% failures with name brands. 50% failures with off brands.

5 differnt writers, none over 4 years old.

Slower speeds seem to help somewhat.

Never cleand a CD drive with anything other than compressed air
