There might be an even better alternative than lzop, specially when it comes to cpu time. I´am not into academic overoptimization but it seems that´s worth testing under reallife conditions.

Great topic, will follow this. I would love faster backups and restores!

We been using the pzstd and it really works great. This is such a simple feature for Virtualizor to build in and has the largest quality of life benefit with regard to backups. I simply do not understand why they have not built this in yet. Agree with this ----------------------- jasa install vps | vps managed |

@chirag @softaculous
When can we expect zstd support for backups in virtualizor? - Dave |
