These things above are essential. I suggest for extra paranoia that you keep a statically linked copy of the matching restore to the dump you used to create the backup handy. Sometimes Ill bzip up the dumps so Ill keep a bzcat handy too. I had a situation when trying to restore a dump made with a 5.1 dump with a 5.0 restore. There were multiple errors until I used the right one. Note that this could be coincidence or the malice of inanimate objects and could never happen to you. I prefer belts and braces. I also suggest that you do a practice run dumping a machine, destroying it, then restoring it. There is nothing worse when the panic button has been pushed than realising that you dont know what you are doing. Remember your job and maybe the company is riding on that restore working.
