Hi All,
All my data is stored on a separate device/partition: a 2TB USB disk with one ext4 partition.
I have 3 more USB disks: 1x 1TB + 2x 500GB = 2TB right ?
I want to backup my data from the 2TB volume to the (older/slower/cheaper) other volumes combined.
I am thinking to use LVM to group the 3 smaller USB disks into one 2TB logical volume and use that to back up the 2TB primary volume. Do you think that is a good idea ?
In case of disaster I can replace the 2TB primary disk and restore from my 2TB logical volume right ?
What happens if :
- I have to replace my internal hard disk and reinstall ubuntu ?
Can I re-attach the logical volume ?- One of the physical volumes of my volume group dies ?
Can I remove it and replace it with a new physical volume (bound to have other dimensions) ?
Understandably I will loose my backup data.... or ?
PS: running Ubuntu 10.10
TIA for any help you can provide,
Best Regards,
johmut
