I own a WangDAT 1300, on which I do my occasional backups. [1] What is the probability that a dump is corrupted if I also create or delete a few files on the volume that I am dumping from? (I do not care about dumping these new files; I only care that the other files are restorable.) That is, I want to work while I backup. [2] Is there a dump verification program that tests for internal consistency (i.e. to detect if the problems mentioned in [1] may show up). I believe "restore t" does not seem to do it, because it only reads the first pass directory and file information, not the actual data information. [3] I currently use dump 1ufs /dev/rxt0 650000 /dev/rsd0a to backup. Is 650000 the correct number for a standard 90 minute DAT tape? I'll post a summary. Thanks for any advice. /ivo welch
