I make also dd if=system_disk of=file and gziped so I have full copy of my system hdd.
But I'm physic more than 250km from my backup and I can't restore this now.
It is possible to extract from gz archive need files and restore omv portal in that situation?
Im not familiar with dd for this task. I always use CloneZilla to make and image of my system disk before this kind of operation, so I know I can do a rollback if anything fails. Especially when upgrading to a 3.0 beta version.
Im not the best to tell you which way to go forward now. Reinstall is one option but I dont know if ryecoaaron has an better idea?
