Our current system setup sees each server backed up by 3rd party software(Veeam). The backup for our Database server occurs once each night.
Alongside this, there is another 3rd party tool that performs database replication to a backup SQL Server.
As it stands, if a disaster were to occur then we automatically switch over to the replicated backup SQL Server. Then switch back once production has been fixed.
I am not sure if this is enough for DR. All our databases are currently in Simple mode. I feel that they should be in Full recovery mode, and Full/Differential/Log backups should be performed on a regular basis.
Or is the replication and Full backup enough for DR? I am basically trying to put an argument together in favour of Full/Differential/Log backups.
