General Support - Back up a hard drive to DVD in Kanotix

Titel: Back up a hard drive to DVD in Kanotix

Is it possible to back up your hard drive to a DVD, such as by creating an image of the hard drive? The DVD holds 4+ gigabytes, my HD currently has 2GB of data on it.
Thanks.

Freshmeadow,

You also might want to have a look at Dkop. A nice GUI for making backups to DVD.

not sure if dkop or mondo can span multiple DVD's (if you have a lot to backup) ...can they?

buy an external hard drive instead...they're so cheap nowadays that it's not worth backing up to DVDs any more...seriously...

A DVD has advantages if you compare it to a hard drive, for example if you throw it on the ground ( of course with as less power as possible.. ), it won't be destroyed, a hard drive can be damaged more easily. Backup also means that the different backups should also use different types of media on which they are safed, as every type has disadvantages. So, as DVDs are cheaper than an external hard drive, why don't back up on it?
The DVD-ROM also allows the use of different generations of backups, which most people forget if they use a hard drive.

I actually have two external hard drives that I back up to and I rotate them. They each store 3 versions of backups, so I have roughly 2 months of rolling backups on both drives...

well, the problem with such a solution is, that in case of a destroyed harddrive three backups would be lost. So, as a thumbrule it's safer to store only one backup on one drive. for example, if you store the latest 3 backups on that external harddrive and they all get lost, you'd have a huge problem. Or, if you backup your data incrementally, and your harddrive with the oldest 3 backups is destroyed, also the other backups would be useless.

Very true on losing backups on the alternate drives. Everything has tradeoffs...

Mondo is great for total backups, when you want to be ready for a nuclear war or something. But for just backing up a partition, you might look at partimage. Mondo seems (at least when I used it a couple of years ago) far too cumbersome for repeated backups. I'm not sure it does incremental backups, either, which is a killer point for me.

Good luck!

Mondo is a very well tested and professional backup tool but perhaps not so easy to implement. Both mondo & dkop have very good documentation. For dkop you need to dl the tarball and read the included 18 page .pdf Dkop can span multiple dvd's and do incremental backups.

Mondo can do incremental backups, as well as span disks. I used it for several years, and found it easier to just generate DVD .ISOs, and keep them elsewhere. At that time, DVD media was expensive. The integrated Mindi kernel that it uses can also be very useful to generate a custom boot CD, with all of your existing drivers and partitions.

Eventually, I went to tape instead, but still keep a Mondo boot disc around for disaster to restore from tape.

Mondo/Mindi need quite a bit of free space for temp depending on how much compression you choose. 2 gig HD should be no problem, but a drive 85% full will need some temp space somewhere (you can use NFS mounts on other machines for that).

Thank you all. I am going to try MONDO first. (P.S. I am using a DVD RW to backup instead of an external HD because my wife bought me a DVD RW for my birthday this week!)

From what I've read using Mondo (I haven't used it) for DVD/RW backups is pretty good, however it would be nice if there wasn't such a steep learning curve for all of the different methods. Do a Google Linux search on backups & you'll get THOUSANDS of hits! 18 page .pdf document for Dkop? Good grief! I wish there were a good GUI GNU/Linux backup program included with Kanotix. I admit I don't know that much, but why can't that be done? Linux needs a good backup utility with incremental capability to different media sources. Just Like K3b is based on cdrecord, it might be based on rdiff-backup with choices of medium. I dunno...
