When my recording video storage was full. The previously record will be overwritten. What’s the size/time of record will be overwritten when it happened? By mins or hours units will be deleted?
From the Milestone XProtect Advanced VMSproducts Administrator Manual:
The oldest data in a database is always auto-archived (or deleted if no next archive is defined) when less than 5 GB of space is free. If less than 1 GB space is free, data is deleted.
A database always requires 250 MB of free space. If you reach this limit because data is not deleted fast enough, no more data is written to the database until you free up enough space.
The actual maximum size of your database becomes the amount of gigabytes that you specify, minus 5 GB.
