I'm wondering, does anyone know of any timing tests for pg_dump?
I am trying to find the fastest way to do our nightly database backups
using pg_dump. And I just wanted to make sure I don't reinvent
the wheel if someone has already done a bunch of comparisions with the
various ways to backup.
Here are the kind of timings I'm looking at:
pg_dump -Fc -Zx
pg_dump -Fc
pg_dump -Ft
pg_dump
pg_dump -Fc | gzip > backup
pg_dump -Ft | gzip > backup
pg_dump | gzip > backup
pg_dump -Fc | bzip2 > backup
pg_dump -Ft | bzip2 > backup
pg_dump | bzip2 > backup
I know there are many variables, but I'm just looking at the pg_dump
process. Does anyone know what the fastest pg_dump would be?
Also, what -Z compression level equals the compression of gzip?
I've played with -Z9, but it seems to compress better than gzip (but
takes a bit longer).
Thanks,
Chris
