Hello,
We're playing with M. Rozas' shell script to check the integrity of
backups. Nothing big came out, until :
Tue 3 Nov 05:06:55 CET 2020
cpool/4e
pigz: skipping: cpool/4e/00/4f0068ee33d2c1634ceb1a55b0dd28fe empty
ZLIB/PIGZ ERROR: 4f0068ee33d2c1634ceb1a55b0dd28fe ->
d41d8cd98f00b204e9800998ecf8427e
CHECKSUM ERROR: 4f0068ee33d2c1634ceb1a55b0dd28fe ->
d41d8cd98f00b204e9800998ecf8427e
Using
https://github.com/backuppc/backuppc/wiki/How-to-find-which-backups-reference-a-particular-pool-file,
we tried to pinpoint what this cpool file points to.
ll cpool/4e/00/4f0068ee33d2c1634ceb1a55b0dd28fe
-r--r--r-- 1 backuppc backuppc 0 Dec 27 2018
cpool/4e/00/4f0068ee33d2c1634ceb1a55b0dd28fe
That's an old file. And
BackupPC_poolCntPrint cpool/*/poolCnt | grep
4f0068ee33d2c1634ceb1a55b0dd28fe
4f0068ee33d2c1634ceb1a55b0dd28fe => 0
(we scanned the full cpool, not only the 4e directory, just for sake).
The file is not referenced anywhere in any backup, or at least that's
what we understand.
Shouldn't unref'd cpool files be deleted during nightly cleanup ? We
have $Conf{BackupPCNightlyPeriod} = 1
And can we just delete it ?
Best regards,
