...
The backup result has the time the backup was created and the time when the backup will expire.
When the backup expires, Abiquo uses the expiration time from the backup result, to set the stop time in the backup billing table.
...
The expiration time is set by the property that applies to the current backup policy. So veeam.maxrestorepoints is the main default value. Then if you create a new Hourly backup policy called Hourly, in case the if retention for this the hourly schedule is not set as a Veeam property, Abiquo uses the default of veeam.maxrestorepoints.
If you create a new Daily policy Daily policies called POLICY1 and POLICY2, and you have veeam.maxrestorepoints.schedule.daily and veeam.maxrestorepoints.policycode.POLICY1defined in you Veeam properties, then your veeam.maxrestorepoints.policycode.POLICY1 = 8 and veeam.maxrestorepoints.policycode.POLICY2 = 3124 have priority over veeam.maxrestorepoints.schedule.daily = 31, so if your policy code is POLICY1 or POLICY2, then Abiquo will use the values for these codes. Otherwise, Abiquo will use veeam.maxrestorepoints.schedule.daily = 31 as the retention value.
