Hello,
Would you be able to confirm for me that a host level LVM snapshot of the P=
GDATA directory along with PG_WAL directly via LVM backup is supported way =
of backup and restore?
I read about this here: https://dba.stackexchange.com/questions/145361/back=
up-standby-database-using-lvm-snapshot
Is it as simple as:
? SELECT pg_start_backup('Begin LVM Backup At xyz');
? Do LVM backup from o/s end to backup PGDATA/PG_WAL
? SELECT pg_stop_backup();
Thanks.
Dan
