Hi Samuel
thanks for the gathering this info. Ill look into the bscan issue as
well though i think this might be a known issue.
Regardless, regarding your actual issue: The bscan output shows that
File 3 is missing its attributes (it has no stream 3).
This confuses the director as it never got told that file 3 now started
getting backed up and this is why you get the warning
message from the director.
The same is happening during the restore: the filedaemon never got told
that now a new file was started (because it never got the attribute stream)
so it basically merged both File 2 and File 3 into one file. Even with
this in mind, i think the restore should have caught that and issues a
warning.
Ill look into why this did not happen.
If you add up all the data records (stream=2) with fileid=2 and
fileid=3, you will get 738212473 bytes, which is exactly what the
filedaemon reported
as size for file 2. Since the log contains the size it expected i
imagine that you could manually restore file 3 by splitting file 2 into two.
Can you check which file fileid 3 corresponds to ? Is it a special kind
of file or just a normal one ?
Ill try to see if i can reproduce your issue in the copy system test.
Do you do a local copy (so copy to the same sd) or a remote one?
Kind Regards

Hi Sebastian,
After looking at the logs some more I noticed that all jobs with this
warning have in common that they're using compression (LZ4) and
autoxflate on replication.
Perhaps this combination is still not entirely fixed yet. I'll try
disabling autoxflate in the coming days.
The entire result of bscan is in the attachment. However here's the
last part of it where bscan seems to abort (?):
$ sudo -u bareos bscan -b md5_digest_error_copy_only.bsr
--list-records TapeDevice2 2>&1 | tee records.txt
...

SessTime=1707222936 for EOS record.
Records would have been added or updated in the catalog:
0 Media
1 Pool
0 Job
0 File
0 RestoreObject
23-Feb 12:05 bscan JobId 0: Releasing device "TapeDevice2"
(/dev/tape/by-id/scsi-35000e111c71ac0bf-nst).
I also tried restoring the copy which ends in error.
Most files are restored successfully except for one file which happens
to have FileIndex=2 (corresponding to the `attributes=2` in the warning?):
Enter SQL query: select path,name from file,path where jobid=94146 and
fileindex=2 and file.pathid=path.pathid;
+-----------------------------------+--------------------------+
| path | name |
+-----------------------------------+--------------------------+
| /var/backup/old/2024-02-07_23:30/ | backup_www_1100CC.tar.gz |
+-----------------------------------+--------------------------+
A full restore of the original non-copy backup jobs works fine, as do
restores of other copy jobs on tape of filesets that don't use
compression.
The original job that was copied (93682) doesn't exist anymore; I
think it was an always-incremental consolidated incremental backup
which got consolidated again the following day.
Best regards,
Samuel
