Re: Need solution for weekly database "snapshot" - Mailing list pgsql-general

Setup a slave.

 

Not bad, but the transaction logs would fill up the file system. Besides, it would not be worth it to set up a whole database cluster just for this purpose.

Any alternatives?

if your file system supports it (ZFS, for instance), you /could/ take a volume snapshot/clone, and then mount that and run a separate instance of PostgreSQL on it, using a different port number.  when done with your reports, you'd drop that instance and snapshot.

we run a separate server (hardware and database) for our reporting systems as their workload is heavier than the realtime transaction system.
