let me repeat that question, it was important:

*Is BackupPC_nightly actually being run?*

Yes, that should of course be WakeupSchedule. Sorry about the typo. Note that
the '7' is in there twice. I don't know if that may be confusing BackupPC. I
don't think it should, but the code in question is confusing me right now :).

Yes, but we should first make sure the code is in fact being run.

Actually, it's the other way around. find() is using GetPoolStats() to scan
the pool.

What file system type is your pool on? Have you recently installed IO::Dirent?

How do you know? Is SElinux enabled? Do you notice anything special about the
permissions of the cpool/X/Y or cpool/X/Y/Z directories? Anything in the
system log files? Have you run an fsck?

Well, BackupPC_nightly is supposed to traverse the pool :-). It should look at
all files under the starting directory ($TopDir/$pool/$dir - which is of the
form /.../cpool/X/Y) and queue all single-link files for deletion and chain
renumbering.
