Recently I have been spending time on improving the performance of bupstash (my encrypted backup tool), and wanted to compare it to some existing tools to try and find its relative performance in the backup tool landscape.

This post compares bupstash, restic, borg backup and plain old tar + gzip + GPG across a series of simple benchmarks.

What do all these tools have in common?

• They encrypt data at rest.
• They compress data.
• They have some form of incremental and/or deduplicated snapshotting.
• They are all pretty great backup systems.
