Truncating transaction log without db backup in a virtual environnement where backups are relying on snapshot of halted systems.

Hello,

I have several virtual sql servers having all their storage on a SAN.

A a backup, each night, I :

- Stop the vm

- Take a snapshot on the storage

- Start the vm

For restoring I have just to retrieve and remount the right .MDF/.LDF file from my snapshots collection.

--> backups of several TB of data are taking in few minutes.

The issue is with the transaction log for database ruinning in full recovery model.

Transaction log are growing continuously as I can't perform a transaction log backup as I don't have any database backup.

Any idea how to, when I restart my vm after the snapshot, truncate the transaction log in a way MDF/LDF pair remain usable to restore at a certain point of time ?

Thanks in advance for your advice.
