What triggers full backups on unscheduled days?

[camjohnson]

My backup directory contains full backup sessions on days when they are not scheduled in the zimbra crontab. These sessions are labeled full not incremental, and are not really full. A zmbackupquery for a specific account finds nothing, but the fulls scheduled by the crontab contain all accounts.

Does anyone have a clue as to what triggers these?
