kind borg and other tools benchmark report

[deajan]

Hello,

I'm currently doing benchmarks for deduplication backup tools, including borg.
I decided to write a script that would:

• Install the backup programs
• Prepare the source server
• Prepare local targets / remote targets
• Run backup and restore benchmarks
• Use public available data (linux kernel sources as git repo) and checkout various git tags to simulate user changes in the dataset

The idea of the script would be to have reproductible results, the only changing factor being the machine specs & network link between sources and targets.

So far, I've run two sets of benchmarks, each done locally and remotely.
You can find the results at https://github.com/deajan/backup-bench

I'd love you to review the recipe I used for borg, and perhaps guide me on what parameters to use to get maximum performance.
Any remarks / ideas / PRs are welcome.

I've also made a comparaison table of some features of the backup solutions I'm benchmarking.
I still miss some informations for some of the backup programs.
Would you mind having a look at the comparaison table and fill the question marks related to the features of borg ?
Also, if borg has an interesting feature I didn't list, I'll be happy to extend the comparaison.

PS: I'm trying to be as unbiased as possible when it comes to those benchmarks, please forgive me if I didn't treat your program with the parameters it deserves.

Also, I've created the same issue in every git repo of the backup tools I'm testing, so every author / team / community member can judge / improve the instructions for better benchmarking.
