Hello Frineds,
i wannt to get postgresl cluster file system level backup.
My scenario is like this:
*1.Step ) Pre Synchronization*
rsync -avHK --delete /var/lib/pgsql/ /backup/pgsql/
*2. Step.) Stop Service for consistent Backup *
systemctl stop postgresql-9.5
*3. Step.) Make File System Level Backup*
rsync -avHK --delete /var/lib/pgsql/ /backup/pgsql/
*4.Step.) Start Service Again*
systemctl start postgresql-9.5
*In This Scenario *
*I ask to you , can we lock all databases for write , delete and update
query during the backup Instead of stopping the service. ??*
