Hi Jamie,
If auto log backup is enabled (DBMCLI: autolog_on), backup is started when:
- Log backup segment is full (default: 1/3 of log area)
- Time interval defined in backup template passed
However, there is another condition which must be met and this is, that there must be at least some committed data in log area. Otherwise, it doesn't make any sense to perform a backup.
To check related settings using DBMCLI, following commands may help:
- autolog_show
- info log
- medium_getall
First command shows if auto log is enabled, second one displays information about the used space. Third one shows the interval for auto log backup. Search for medium/template of type AUTO (3rd column) and check the last column. It is the interval in seconds.
Regards,
Palo
