Using the Veeam Explorer will perform a point-in-time recovery WITH RECOVERY, but I don't believe it would be possible to do a point-in-time recovery WITH STANDBY using the Explorer.
Basically the Devs want to check the database data state at various points in time. So ideally we restore the database to a point-in-time at the start of the problem, WITH STANDBY, and give them the transaction log backup file. They can then perform successive transaction log restores, advancing the recovery point, allowing them to inspect the database over the time. When the database is in STANDBY, it's read-only and you can apply more transaction log restored.
The alternative is to do 20+ full point-in-time recoveries of a 200GB database.
Thanks in advance.
