I've got a new install of BackupPC 3.3.2 installed from the Debian 10 apt repository. My
/var/lib/backuppc volume is 15TB, and BackupPC currently has ~480GB of data on it.
However, the front page graph and "Other info" summary both say that the pool
is only 1.93G, and has done since the server came online about 16 hours ago.
How does it calculate what's currently in the pool? I'm wondering if something
somewhere has got stuck.
% df -h /var/lib/backuppc
Filesystem Size Used Avail Use% Mounted on
backups 15T 481G 14T 4% /var/lib/backuppc
* The servers PID is 31493, on host bk, version 3.3.2, started at 2020-02-27
00:40.
* This status was generated at 2020-02-27 21:28.
* The configuration was last loaded at 2020-02-27 19:00.
* PCs will be next queued at 2020-02-27 22:00.
* Other info:
o 22 pending backup requests from last scheduled wakeup,
o 0 pending user backup requests,
o 0 pending command requests,
o Pool is 1.92GB comprising 133570 files and 4369 directories (as of
2020-02-27 01:00),
Probably at 01:00 BackupPC was running only for 20 minutes. That is why it was
only 1.92GB at that moment.
o Pool hashing gives 4 repeated files with longest chain 1,
o Nightly cleanup removed 15 files of size 0.00GB (around 2020-02-27
01:00),
o Pool file system was recently at 4% (2020-02-27 21:24), today's max is
7% (2020-02-27 11:30) and yesterday's max was 1%.
15TB * 0.04 = 0.6TB It is likely that it was correct at that moment.
I have no idea if this is related to the misreported pool size, but it suggests
to me even more that something somewhere is stuck. What should I be looking at?
You should be looking at time stamps. Wait for the next nightly run (01:00
tomorrow) and recheck pool usage statistic again.
