What is the best backup method (full,incremental, etc...) to take a DB backup?
Any versions
Regarding the product's side, any backup method can be used to perform the DB backup.
The only thing needed is that after finishing the restore, the DB must be in an integer state, without data being lost/corrupted.
So, the only general recommendation is to periodically test the restore of backups done. This is a general best practice in IT world.
