[ADMIN] File system level backup

[Ganesan Kanavathy]

Dear all,   All the while I was doing pg_dump as backup method for my pgsql db. Today I came across File system level backup on Postgresql Documentation.   After reading it, I am quite unsure whether File system level backup is better than pg_dump.   Furthermore, do we really need to do File system level backup or pg_dump is good enough?   Any suggestion is much appreciated.   Regards, ganesh
