I'm using Red Hat Enterprise v2.1 and PostgreSQL v7.3.4. Our hardware
setup includes a large Storage Area Network (SAN). The systems folks
are going to utilize a snapshot type backup to backup the file system.
This snapshot will include PGDATA and all the PostgreSQL files. My
question is if I restore this snapshot will PostgreSQL work? I know if
doing a typical file system backup of PostgreSQL I must first stop the
postmaster or the backup will not produce a useable PostgreSQL system.
Is it necessary to stop the postmaster for this snapshot backup also?
