I recall having this issue restoring on the Amanda server where
the client machine user had a different UID on the server, and
somehow after tarring up the temp restore directory on the server,
and rsyncing it back to the client, the files ended up with a
different uid than how they originally were on the client.
I suspect Amanda's invocation of tar doesn't use --numeric-owner,
so if bob is UID 1000 on machine A and UID 2000 on machine B, and
you backup bob's files on A and restore on B, then move them back
to A, they end up owned by 2000 on A, which is not bob on A.
Or possibly I screwed up somewhere and wasn't aware of it. I just
'chmod -R' the directory and didn't investigate it further at the
time.
