A VSS writer just prepares a snapshot of the (virtual) machine while pg_basebackup make actually a (safe) copy of the cluster - important differences are that VSS writer 1) is called by the operating system, 2) is much faster and 3) does not need space for a complete backup. But you are right: if you can ensure that pg_basebackup has finished prior to making a backup of the virtual machine, this is certainly safe.

The virtual machine is managed by the customer. He does backup the VM. Is this enough, is this safe? When you run MS SQL Server on Hyper-V / Windows, the SQL Server provides ist own VSS writer responding to a taking a snapshot. This ensures that the image oft he SQL database is in a safe stake when the backup is written. I may be wrong, as I don't know MS SQL Server, but in the way you describe it, you make me come in mind pg_basebackup(). -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
