I am installing a backup system to handle the backup of a four machine network. To enable backup machine to have access to the remote filesystems, I am running the whole thing over NFS. To ensure that the backed up files haveees the same ownership atrributes as the original, I am also using the ugidd daemon which maps remote uids to local uids. The dilemma I am now facing is that for some remote uids there is no corresponding uid on the local machine (i.e. that user simply doesn't have an account on the local machine). Is there someway to get around this problem so that original ownerships are retained apart from having to make sure that there is an entry in the local machines /etc/passwd 's file for every account on each of the remote machines. This seems to be a bit of an unreliable fix anyway as it doesn't cover the event of a new user being added to one of the remote machgines without extra entries being added to the local machines's passwd's file again everytime this occurs = big maintenance hassles. Am I going down the wrong avenue by using NFS anyway?? Please help me - it's 2:45 in the morning and I dont want to lose too much more sleep over this!! BTW, I highly recommend the Trainspotting soundtrack as a good hacking efficiency booster. Doug PS Please send replies by email and I will be bogged down in end of year study for the next two weeks and won't have much time to check the newsgroups.
