Lesson #1: Never ever put the holding disk area on the backup disk holding the vtapes, it just pounds the seek mechanism of that drive leading to a potential early failure. I've always put it on the main drive, but that then subjects the main drive to the same abuse only when backing up the main drive, and I'm supposedly backing up 4 other machines too. TBT I will have a drive that is not in current use when the new machine is built, and which may well be an even better solution. Set up that way should also be a measurable speed improvement. Lesson #2, I just learned today that the raspbian AND debian buster 10.2 versions have NO inetd or xinetd. Ditto for RH. So that probably explains why I can install the clients and configure them to be backed up, except the clients crash about 3 seconds after the server first accesses that client, leaving NO clues in the logs of the crashed machines. I've had it happen to an armbian jessie install on a rock64, an rpi3 with a 64 bit debian buster install, and I expect it will be the same should I try to backup the raspbian armhf install on the rpi4. This machine I pulled out of the midden heap in the garage so I at least had email, is so crippled I've turned amanda off until I can get a new machine built and this boot drive moved to it. Got the cpu today, might have the rest of it tomorrow. The tower has smoke stains from the fire but that won't hurt it a bit. Anyway, we've got to figure out what to do about the missing #inetd stuffs or its all going to die as folks update. Copyright 2019 by Maurice E.
