Hi Team,
Production database Backup is running very long hours. Any option to reduce backup time? Kindly advise me.
DB size: 793 GB
We are taking pg_basebackup backup.
do you see network saturation, io saturation ?
generally faster hardware i.e striped and or nvme disks along with a robust network link and capacity should help get the backup done quickly.
where are you taking the backup from? is the server busy doing other work or it is a dedicated machine for backups ?
basically monitor for resource saturation, if all looks good, we could take basebackup of a 10tb db in 8 hours, and in another case on a slow remote storage, backup of 2tb took 1 day.
now, pgbackrest can speedup backup processes by spawning more workers for archiving and stuff. we have taken backup on nvme disks striped of 28tb in 3 hours, bare metals servers with powerful cpu.
so , it's hardware .... else switch to pgbackrest which can take incremental/differential/full backups.
there are other tools too, I used only these two.
