Hi Team,

I just recently purchased the True Image 2014 and one of tests I did was to back up my 290 GB office laptop that uses Red Hat Enterprise Linux 6 Open Client software . I created an Acronis USB boot disk and used that to do a sector by sector clone of the laptop's disk to an external e-sata 500GB disk.

After the cloning was complete, I mounted the e-sata drive as the primary boot disk but I just get a blinking cursor during startup. It doesn't even ask me for a LUKS boot password. Later I booted normally and I used the gparted utility in Linux to compare the internal (original) disk and the external (e-sata connected cloned disk), and the partitions are the same.

Is there any other post cloning step I could do to make the disk boot?

Or perhaps more important, are there compatibility issues between Acronis and Linux encrypted (where it requires LUKS password) disks?

Thanks and regards.

Hmm .. I found your posting while hunting for Acronis LUKS support. I've been doing a LOT of clonezilla cloning with LUKS volumes and I'm moving over to Acronis to try and avoid issues exactly like you describe. I keep hoping Acronis will implement LUKS support to allow us to enter a luks passphrase and then have it clone the internal contents of drives and then rebuild luks on the restore and dump the contents inside. I only want to copy what's used vice having to do a block copy of the whole drive. Drives me nuts spending 8h doing a slow 1TB LUKS drive when there's only 80G in use :-) .. ANYWAY..

the issues you describe I've had after some clonezilla restores.. a lot more with RHEL 6 images than with RHEL/CENTOS 5.x machines.
It can be a lot of issues. You may want to get rescatux or super grub disk (iso live cds) and see if their grub repair stuff can fix things for you. I've had about 50/50 success with it. I usually have to go to a site like this: http://www.dedoimedo.com/computers/grub.html, zip down to the "Installing grub natively" and run through the commands to fix grub manually..sometimes mounting my root and boot drives manually and doing a grub-install --root-directory=/mnt/root (from a livecd) works.. sometimes i have to get grub re-written to the boot blocks manually, boot into a dumb grub, and re-setup the drive manually (something like setup (hd0) ..

It can break in a lot of different ways.. and I haven't seen what you're describing with acronis yet so .. You'll have to experiment.
