I am trying to be green and put our backup servers to sleep during the day and have them wake on LAN and fire back up at night for our nightly backups as "sleep" is a sort of low power usage mode.
I can not comment on how to do what your asking but I can see one potential problem. If your solution involves booting the backup server and during the boot an error is detected in the filesystem check the boot process will halt waiting for you to manually correct the problem. Of course you can avoid the problem by making your backup scripts on the primary server can implement a time limit on the wait for the backup server and if the wait times out then skip the backup.
Someone out there more knowledgeable then I (and there are many<g>) may be able to suggest a way to alter the boot to avoid the filesystem check (or the halt).
I would not disable the filesystem check at boot. Those checks are needed. You can lower the frequency of checking using tune2fs (not needed to check after a certain number of boots if you boot daily). I think it is good practice to check your backup status on a regular basis anyway. You would notice a problem with your backup server in this way.
