Supporting compression on volume backups #3566
Description
To Reproduce
it would be helpful to gzip compress volume backs when used via https://docs.dokploy.com/docs/core/volume-backups or have an option to do so. Especially for use-cases like sqlite where the backup sizes will greatly reduce storage.
Current vs. Expected behavior
volume creates only create a tar file - application/x-tar - but a .tar.gz would better utilise storage space on s3

Surprised it is not compressed by default.

Totally agree with this.

I've opened PR #5206 with gzip compression for volume backups (
tar cvf→tar czf,.tar→.tar.gz). Tested locally with MinIO as S3 destination — backups compress ~15:1 for text/JSON/SQLite data.I also explored zstd and shared the findings in the discussion #2991 — including the trade-offs and a proposed path forward if the team wants to go beyond gzip.
