Hi
I used BackupPC since decades for a dozen of PC (Linux and Windows)
using rsync/tar through ssh. Some hosts are connected through ADSL
connection. It works perfectly well and fully fit my needs.
Recently I decided to duplicate backuppc data on a remote mini server
(OrangePi+2E + 1TB HDD). I created a script to rsync the cpool
directory separately (rsync spended too much time to compute diff
because of the low data rate link). It takes 2 months for the initial
replication! Anyway, it's done and incremental synchronization should
be done in less than an hour per day.
Now I want to start the BackupPc daemon on the replicated data to ease
backup access. So I need to avoid any nightly pool cleaning (it will
be done by my rsync script) and disable backup from any hosts. I use
this configuration settings:
$Conf{WakeupSchedule} = [];
$Conf{MaxBackupPCNightlyJobs} = 0;
$Conf{PoolSizeNightlyUpdatePeriod} = 0;
$Conf{PoolNightlyDigestCheckPercent} = 0;
$Conf{RefCntFsck} = 0;
$Conf{FullPeriod} = -1;
$Conf{BackupsDisable} = 2;
$Conf{EMailNotifyMinDays} = 365;
I'm confident with disabling host backup feature but I'm not sure
those settings fully deactivate nightly pool cleaning. Can someone
correct it ? Thanks in advance
I added my synchronization script and the associated crontable. Every
thing is running on same account (backuppc user).
