If by "nodes" you are referring to the individual machines in your responsibility tree, then yes, we agree. With only 3 such nodes to pick from, and with the widely varying amounts of data, its not quite as practical. With only 6 DLE's, I'd have 5 backups of around a gigabyte maximum, and one at around 350Gb. But Jon tells me the softlinks are backed up, while my amrecover of one subdir with all the important gcode and machine configuration files in it, less than a week ago, restored exactly zero of the 3 or 4 softlinks in that lathe:/home/gene/linuxcnc subdir. I had to re-create them from scratch. If they were in the backup, and the log (as I posted earlier says they weren't, they were skipped,) then amrecover should have re- created them for me. It did not because they were not in the backup, they were skipped due to the perceived by tar, different filesystem error. Thats the error I'm preaching about, that link did NOT point to a different filesystem, but tar says it did. And that is the bug I am standing on the stump yelling about. > When I want to archive a set of tapes containing ALL the level 0s, > then I do a separate config that says “all 0” and yes, THAT takes > more tapes.

Completely, totally, lost in the noise created by however many email messages have come in on a given day, how many have been read, and how many have been expired. > BUT forgive me if I’ve missed your point! Perhaps we have differing > philosophies of how to use amanda. No, at the end of the day, we are on the same page Deb. Its a matter of scale of course and that cannot be helped. I just want my softlinks to actually be backed up, without any dereference, and its not even with tar 1.27.1 happening. Thanks Deb.
