Re: pgBackRest for a 50 TB database

Hi Stephen

No, I did not try that. Let me try that now and report the numbers here, both in terms of size and time taken.

Thanks for the suggestion.

As said above, I tested pgBackRest on my bigger DB and here are the results.

Server on which this is running has the following config:

Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                36
On-line CPU(s) list:   0-35
Thread(s) per core:    1
Core(s) per socket:    18
Socket(s):             2
NUMA node(s):          2

Data folder size: 52 TB (has some duplicate files since it is restored from tapes)

Backup is being written on to DELL Storage, mounted on the server.

pgbackrest.conf with following options enabled

repo1-block=y
repo1-bundle=y
start-fast=y

Thanks for sharing!  Did you perhaps consider using zstd for the compression..?  You might find that you get similar compression in less time. 

Thanks.

Stephen
