I need assistance restoring a backup disk image created using partimage and these instructions (http://www.psychocats.net/ubuntu/partimage). I attempted to upgrade an old P3 server running dapper but hosed the machine (kernel panic). Now I want to restore my dapper backup image.
So far I've done the following:
connected an external USB drive to the old P3 server that contains the backup images
booted the old P3 server using a rescue cd (which includes partimage).
noticed numerous buffer i/o errors during a long boot process
entered "df" to check whether the external drive mounted automatically--it didn't
ran:
mkdir /mnt/sdc1
mount -t ext3 /dev/sdc1 /mnt/sdc1
Ran partimage
partimage
Selected sda1 to restore and followed these instructions (https://wiki.ubuntu.com/Testing/Backing_Up).
After identifying the image to be restored, I hit F5 to continue.
Partimage terminates with the following error: "invalid compression level for /mnt/sdc1/atlas-backup-image/atlas-sda1.000" This partition is about 3G.
Are my partitions too big?
Part II - I purchased a new duo core machine and plan to migrate the server settings from the P3. Can I restore these images on the new machine? Should I try upgrading the P3 again before migrating? Should I do a clean install of 8.04 on the new machine and then try to migrate the application settings?
