Now that the price of a Dual layer DVD writer has fallen to approximately the cost of three TR-5 tapes, I am looking at dumping the TR-5 tape drive and getting a DVD writer for backups. Does anyone have recommendations on brands, pro or con. Media life figures for RW media. And backup packages? I've been using AMANDA fairly successfully, but am open to other packages. TIA, Jeffrey

There is one problem with using DVD's for backup and that is that the normal DVD file system, doesn't support files larger than 2 Gb. This means, that you can't use the DVD drive as a replacement for a tape. Another problem is, that even if the DVD unit is dual layer, I've yet to find public DVD's that support dual layer, and certainly no DVD writer (public one) that does. So you're still stuck with 4.7Gb DVD's. If you do know of any linux backup software, than can backup "directly" to a DVD, and read "directly" from one. Let me know, I'm interested in the subject as well. Got myself a DVD burner for the very same reason.
TIA, Jeffrey

I saw some double layer blank DVD's in Hamburg, Germany in a public shop.
I think, you simply have to use backup software that can devide the backup into multiple files of a certain maximum size. As far as I know, that exists, even though I couldn't name one right now (except that tar usualy should be able to do it too). Martin

Also, it looks like Mondo is back up online. Check here: http://www.mikenjane.net/~mike/ I think Mondo will do backups to CD or DVD. The man who created X-CD-Roast also has a backup app just for DVD's IIRR.

I'm using DAR to backup to DVD+RW's. DAR will make up 'slices' of your data in any size you desire (I fill the DVD) and will do compression at a level of your choice. You can also includes filetypes from compression (such as *.jpg). The one problem I have found using DVD's for backup is that they *do* get scratched over time and they are prone to read and/or write errors. I am now doing comparisons of each DVD after I write it to check the integrity. But the speed is nice.
Will either amanda or mondo handle dual layer DVD? I am considering a Lite On drive which can burn both CD and DVD media. I have a Lite On CDRW. -- _______ _______ _______ __ / ____\ \ / / ____|_ _\ \ / / | | \ \ /\ / / (___ | | \ \ / / | | \ \/ \/ / \___ \ | | \ \/ / | |____ \ /\ / ____) |_| |_ \ / \_____| \/ \/ |_____/|_____| \/

In the US, DVD Dual Layer media run about $10USD apiece. And they are write-once. A bit expensive for backup, IMHO. For AMANDA, I think the answer is yes. All the pieces say the right words, but I haven't actually tried it. Jeffrey

Gee, that's odd. I have a dual layer LG DVD RW that works quite well for dual sided disks. Price was ab out $80 or so. The only real drawback is buying the dual layer DVD's. They are about $10 or so right now. The SUSE 9.2 dvd is dual layer, and copies just fine with this system.

Tom's hardware guide (http://www.tomshardware.com/storage/20041102/index.html) has a good review on 16x dual layer dvd drives. Alex

The price of DVD Dual Layer media, $10USD each, makes them unsuitable for daily backups. However, 4x speed DVD-RW are just over $1USD each and 1x speed ones are less than half that. AMANDA has ways to backup to CD/DVD, output to file instead of tape and write the file to the optical media. There is also a drop in replacement for the taper module that will backup directly to optical media (see URL below). As soon as the tape drive or a couple of tape cartridges wear out, I'll replace the whole tape mess. Jeffrey http://www.tivano.com/software/amanda/index.shtml

This is good news! Is optical media support new (within the last half year, say), or did I just miss it when I checked out AMANDA back in the middle of last year?

And maybe I'll never have to buy one in the first place.

Yes and no. In the standard AMANDA package, you can select file as the output device. This is from the www.amanda.org Web site. I haven't tried it yet. By setting the "tape length" you get a file that will fit on the CD/DVD. The AMANDA-CDRW taper replacement is a 3rd party component. So no, AMANDA doesn't support optical media directly. And yes, you can use AMANDA with CD/DVDs. Jeffrey Also, there is new, beta documentation on the Web site. Check it out, it's an improvement.

media. And backup packages? I've been using AMANDA fairly
I use BRU (Backup and Recovery Utility) from The TOLIS Group (http://www.tolisgroup.com/). From the command line, it is as easy to use as tar. It also comes with a GUI frontend which I've not used at all, so I cannot comment on it. The reason I use it over tar is because of it's complete data integrity checking. It can use tape/cd/dvd/fs as it's backup media. It's uses cds/dvds as raw devices (no file system), so there aren't any file size restrictions that I've hit. It is a commercial product though. $70 USD or so for the version I purchased. It was worth the price to me. Cheers, eric
