Re: [BackupPC-users] How does BackupPC 4.1.1 calculate Pools size?

The nightly pool check (BackupPC_nightly) only traverses a portion of the pool each night. See $Conf{PoolSizeNightlyUpdatePeriod}. The default is 16, meaning it takes 16 nightly runs to get through the whole pool.

It looks like your installation is quite small, so you could set $Conf{PoolSizeNightlyUpdatePeriod} to 1.

My instance of Backuppc 4.1.1 reports:

"Pool is 26.56GiB comprising 764047 files and 16512 directories (as of 5/1 01:00)"

However, when I check the file system, I get 'slightly' different numbers:

# du -bhs *
50G cpool
2.1G pc
4.0K pool

26GiB vs ~52GB.

The target file system is an NFS file system. Is there something I should be doing different to get a more accurate report of the pool size? How does BackupPC calculate the pool size? (I'm trying to grok the source code, but haven't found the method yet.)

Thanks
