Re: [Xen-users] Re: How to Backup and Restore MBR within Logical Volumes?

Hi,

I don't think I will be using the LVM snapshot method. I will simply ensure that my domU is not running, then I proceed to do the losetup and kpartx procedure. Subsequently I will backup the MBR of my domU by dd-ing /dev/loopX and clone all the filesystems of the domU using fsarchiver.

I would like to use fsarchiver because it can support LZMA compression. LZMA can compress better than bzip2 and decompress 3x faster than bzip2. partimage only supports gzip and bzip2.

A reminder though: don't forget to create a "consistent", unchanging
version of domU storage before doing backup. Either by shutting down
domU, or by creating LVM snapshot first.

Also, if it comes to Windows domUs, I find ntfsclone is better than
fsarchiver. One of the reasons is that fsarchiver can not create
compressed files during restore.
