Description
randomly spreading the backups across the day is only measure currently.
however that doesn't take backup size/time it takes to backup into account, so load/bandwidth usage is not distributed evenly and especially for new backups jobs can run into each other (mainly bilbo & jenkins affected I guess). this can be guarded against withlock
maybe a better approach is to have a single cronjob trigger for all backups, that is then in turn run in parallel with x number of jobs in a matter like
find /etc/rsnapshot/*.conf -print0 | xargs -0r -P 12 -I CONFIG /bin/sh -c '/usr/bin/rsnapshot -cCONFIG sync ; /usr/bin/rsnapshot -cCONFIG daily'
but depending on the headroom this also might need the withlock / some means to prevent running into each other.

Backup will not run twice at the same time, rsnapshot checks for existance of pid file and pid.
