Linux disaster recdovery

[Anand Sreenivasan]

Hello all,
Have any one used mkcdrec for linux disaster recovery. I ran a backup which created a ISO image on a server. When I try to restore this on to a test server, It complains that my harddisk is smaller . I have a 120GB disk and even trying a fdisk to change the cylinders is not helping me. Any ideas is appreciated. Thanks.

Shalom,

There is little you can do with an iso image made with dd.

Try:
http://mondorescue.org
http://www.acronis.com

The second has to be paid for.

I am all about mondorescue. It works great. I will say that you need to be knowledgeable with Linux when trying to move to alternate hardware, or if you run into issues. You have the option with mondorestore to resize filesystems, etc. In a worst case scenario, you can create partitions using fdisk, or even stup lvm. Then run mondorestore and skip the partitioning and do the restore. I have had a couple of occasions where I had to use a rescue cd to fix some fstab entries, and/or reinstall grub. But that isn't very often.

Well I agree with mondorescue, you can edit the disk and partitions to get the restore going, My caveat is I am going to be remote when I have these linux systems restored on a total different hardware and I want to just give one iso image to them and they just boot off it and be done with it. I have lots of linux systems and capturing all these details and sending them would confuse them more. This is more for a DRP than for my onsite linux recovery !!! Any thoughts ??

Supposedly you can do this with acronis. The thing is you are probably going to be hard pressed to find a software that works without a hitch. I am using mondo for DR. The thing is that I am familiar with the kinks of getting a Red hat OS up and running. At this point I just manually do the LVM, restore from mondo, fix any grub or fstab issues, and then boot and run kudzu. The disk restore part isn't that bad if you have the same size disk, or larger. It's when you are confined to a smaller disk that you have to do he work. Dunno, good luck!

mondo is the reference in linux dr for ages, you'll be hard pressed to find a better overal package.
