Thanks Scott for your input, Our database is keep growing and application owner want to have incremental backups daily. Can you share how you have configured the lz4 compression with pgbackrest.  Any special storage requirements?

Best Regards

FYI, Naveed, there's a tradeoff available in current versions of pgbackrest. It can be configured to use lz4 compression. For us, that means close to 50% larger backups than gzip, but many times faster. 3.2TB in 30 minutes, using 8 processes, 725GB backup size--no already compressed bytea, but a good bit of incompressible UUID columns.

Good enough that I stopped doing daily incrementals, and just take full backups daily.
