Hello buddy,

/dev/c0t3d0s6 /usr

I get error when restart after complete full backup
Can't load the root file system
Type 'go' to resume

What is wrong ?
Please help me to make backup OS to spare.

Thanks you and best regards,

Your partitions are all wrong. Slice 1 overlaps slice 0; which means that your root filesystem will get corrupted as soon as the system boots up.
Slice 6 *also* overlaps 0 *and* 1, so your root filesystem is already corrupted when you do your ufsrestore.

Fix your slices on the destination disk and it should work fine.
