Hi,
I’m seeing an issue where the uid/gid of two files inside
the backup are incorrectly root instead of the correct
owner (openldap in this case).
Files on the server:
-rw------- 1 openldap openldap 10485759 Apr 8 2022
log.0000000004
-rw------- 1 openldap openldap 10485759 Sep 21 14:16
log.0000000005
-rw------- 1 openldap openldap 10485759 |Feb 22 10:50
|log.0000000006
-rw------- 1 openldap openldap 8192 Apr 19 2022 memberUid.bdb
Files in the backup (output of BackupPC_ls):
-rw------- 105/107 10485759 2022-04-08 08:38:34

All the other files in the folder have the correct
owner/group. The file ownership isn’t changing on the
server at the time of backup.
I’ve tried removing these files from all the backups and
running a full nightly to (hopefully) clean out something
that’s cached wrong in the pool, but they came back again
the next night with the same issue. Any ideas?
Yes, those are links to the same size thus same content as
the file at the top. The only way to check if things are
correct is to do a test restore to different location and
check the ownership of those restored files. There are
"attrib" files located elsewhere that keep track of the
ownership and source of the file information. When you
manually delete files from the pool you corrupt the backuppc
data base which could lead to future inaccuracies in backups
and restores.
You should read the "How it works" in the backuppc
documentation.
Deduplication is one of the main premises of backuppc.
