Even if there were such files, your ls command wouldn't list them because it looks for files named 'poolCnt' not 'poolCnt*'. :( I recommend getting the hang of the 'find' utility, but be warned that in my experience it's an acquired taste. You could always pipe the output of ls -lR into a pager (or grep) but the right utility will be more efficient. > I also can?t see what caused this to happen in the first place. ... > Can anyone give any insight in to what is going on here ...

BackupPC_poolCntPrint may give some useful information, see e.g. https://sourceforge.net/p/backuppc/mailman/message/36379446/ The syntax isn't always obvious so here's an example using BackupPC_ls much as Craig suggests in his post linked above, to list md5sums on a box backed up here: backuppc@server:$ /usr/local/BackupPC/bin/BackupPC_ls -R -h host44 -n 2072 -s Config / | head /: -rw------- 0/0 0 2013-06-27 13:09:27 /.pwd.lock (d41d8cd98f00b204e9800998ecf8427e) drwxr-xr-x 0/0 0 2021-09-03 14:52:44 /ConsoleKit/ -rw-r--r-- 0/0 1467 2019-01-18 15:26:02 /GeoIP.conf (fe5e3fdcd6ad284bb57e63fe41f4e553) drwxr-xr-x 0/0 0 2015-05-03 19:19:43 /ImageMagick/ drwxr-xr-x 0/0 0 2024-03-20 07:44:44 /ImageMagick-6/ -rw-r--r-- 0/0 4954 2021-01-25 18:10:07 /Muttrc (6793ae4ed35d7fa37a57e2b1fd1507e8) [very big snip] You'd grep your output for a06340ddb577fd02a04bda2998a8d246. There might be more scripts kicking around on the mailing list to do things like this, I can't recall, but sometimes random scripts need bringing up to date. So unless you like puzzles I'd recommend using the tools provided before going off the reservation. -- 73, Ged. |

Hi Ged > Even if there were such files, your ls command wouldn't list them > because it looks for files named 'poolCnt' not 'poolCnt*'. :( Yes, apologies I pasted the wrong command in to my email - I did actually try to find with the wildcard version (unsuccessfully). > Did a machine experience a power failure, crash, or something like > that? Perhaps someone restarted BackupPC at an inconvenient time? > Did you experiment with compression? Manually fiddle with the pool? Certainly not changed any settings or fiddled with the pool in any way. It's possible that the server (cloud based VM) ran in to an issue but I'm not aware of it. > backuppc@server:$ /usr/local/BackupPC/bin/BackupPC_ls -R -h host44 -n > 2072 -s Config / | head Hmm, but I would need to manually run this for every host (50 of them) and every backup? Thanks Jamie |

Thanks Ged, but the pool file is missing, so I don't think any of this helps? Certainly there is no file with the name a06340ddb577fd02a04bda2998a8d246 anywhere in the pool. -----Original Message----- From: G.W.

Found it with:
# a0 is the first two letters of the hash of the file we are looking for:
a06340ddb577fd02a04bda2998a8d246
find . -name "poolCnt.1.a0" -exec sh -c 'for f; do
/usr/share/BackupPC/bin/BackupPC_poolCntPrint "$f" | grep -q
"a06340ddb577fd02a04bda2998a8d246" && echo "Match: $f"; done' sh {} +
Thanks for the pointers!

Well having apparently found the backup that this file relates to:
sudo -ubackuppc ./BackupPC_ls -R -h myhost -n 1437 -s /var/www / | egrep
a06340ddb577fd02a04bda2998a8d246
... returns no results. No results in any share of that backup.
