Re: NOTES: big estimate
Jon, We also see 'big estimate' output for some partitions. I assumed some sort of bounding but never looked into it any further. Reminds me of the O (big-oh) and omega we'd compute for algorithms back in computer science class [upper and lower bounds limits for algorithms]. Something that I suspect is missing from more current programming classes.

Yes, you updated your packages and got tar 1.15.91, which changed
something related to --listed-incremental. I believe there is a
current snapshot of Amanda that addresses that issue, but you might
want to just revert to a previous version of tar, as 1.15.91 also
has an issue with using --one-file-system in conjunction with the
--listed-incremental option that causes it to leak out of the
base filesystem,
Indeed. The only way to get my backups working again was downgrading to tar
from sarge:
apt-get install tar=1.14-2.2
Debian Linux, testing; VERSION=Amanda-2.5.0p2; installed by apt-get.
This is the Amanda host; these DLEs are local disks. The hosts on the
nets are fine.
Does that first entry mean that the level 1 worked but the 2 didn't?

The format for incrementals was changed in 1.15.91. While the new tar can
probably read old incrementals, I guess the old tar can't read the new format.
Probably I didn't suffer from the downgrade since all my level zero dumps were
long overdue, and Amanda no longer wanted to do incrementals.
