Difference between Daily and Interval backup
When scheduling backups you have an option of selecting:
Users have to specify a time when choosing this type of schedule. Syncrify will attempt to run the actual backup as soon as the clock strikes the
provided time. For example, if you chose to run a backup at 6 PM, the backup jobs will be started exactly at 6 PM.
Consider the scenario where the machine is turned off or is in sleep mode at 6 PM. In such case the backup will start running
if the machine wakes up before midnight. It will NOT
run if the machine is turned back on the following day.
Therefore, the backup window for this particular job is from 6 PM to 11:59 PM every day.
It is important to keep in mind that Syncrify will not run a missed backup if the day is different, which is done by design to avoid
running a backup at an unwanted time of the day.
An interval backup will always run as long as the time interval since the last backup has elapsed. Therefore, even if a machine is turned off or put
in the sleep mode, a backup will run as soon as the machine is up and the time since last backup has elapsed.
