The problem has resolved itself. It looks like the root cause was that the portion of BPC which generates the graphs (and also supplies the "Pool is XXXGiB comprising YYY files and ZZZ directories" text in the General Server Information) does not update its information regarding the physical filesystem while a backup is in progress. We have one particularly large storage server which took a week to complete its first full backup on the new pool. That backup finally finished yesterday, and then all the numbers were updated overnight. ________________________________ From: G.W.

Look for $RRDFile in BackupPC/bin/BackupPC_rrdUpdate. You might need to blow away[*] the RRD file and start again. [*] Move to some safe location elsewhere. :) -- 73, Ged. _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
