Kopia’s development has accelerated in 2020 and is quickly approaching 1.0. While a number of new features have shown up within the tool, this post will concentrate on the performance improvements made over the last few months. To do that, we will compare v0.4.0 (January, 2020), v0.5.2 (March, 2020), and v0.6.0-rc1 (July, 2020). We will additionally also compare it to restic, another popular open-source backup tool. All binaries were downloaded from GitHub. With the exception of  the s2-standard compression scheme being enabled with kopia, the default options were used for all tools. //

As can be seen in the above results, kopia’s performance has improved significantly over the last few releases. The time taken to backup 200GiB of data has been reduced from ~840 seconds to ~200! For just a single process, this translates to an effective processing bandwidth of 1 GiB/second and an upload bandwidth utilization of 3.5 Gbps.
