RE: HELP!? Any files I should NOT restore?



Well, since no one responded I suppose I'll answer my own question --
maybe it'll help someone searching the archives in the future.

Keep in mind this restore has only been up for a weekend, so it's still
quite possible I'll find unexpected problems later.

I skipped restoring the following files and directories:
/proc
/boot
/etc/grub.conf
/etc/fstab
/etc/mtab
/etc/lvmtab
/etc/lvmconf
/etc/lvmtab.d
/dev
/etc/hosts
/var/log

The reason I skipped /etc/hosts is that I wanted to be sure changes to
/etc/hosts while the restore was running didn't interfere with the
restore, as the network tape drive is normally accessed using a
dedicated backup subnet that wasn't available during the restore.  I
instead restored this file elsewhere in a second pass just to have it to
refer to.

I didn't restore /etc/fstab because my filesystems changed during the
rebuild.   Again, restored this file elsewhere in a second pass just to
have it to refer to later, especially since I had several complex
network mounts in the original file.

Could've restored /var/log, but 1) I didn't want to overwrite current
logs with old logs and 2) I didn't really need the old logs.  If needed
I'll restore them elsewhere later.

There was no need to skip restoring the backup client software in this
case -- Data Protector clients (not cell managers) require no special
consideration of their client software during a restore.

Hope that helps someone in the future.
