Vykar is a fast, encrypted, deduplicated backup tool written in Rust
vykar.borgbase.comIt’s centered around a simple YAML configuration format and includes a desktop GUI and webDAV server for browsing snapshots. Developed by the same team that created Vorta and Borgbase, I’ve been testing it and it’s quite fast and user-friendly.
From the graphs it seems that the initial naming for it was V'Ger, what would had been a good match with Borg and Vorta in the Star Trek based naming scheme.
It was a bit surprising that, coming from the same team, it didn't use the same repository format, for more or less the same use case and feature list (may it be related to its native support of S3?)
Yeah, I love the original name, but it would have been problematic potentially with copyright. As for breaking the format, sometimes there's good reasons for it. I can tell you that it really flies though, when compared to Borg/Vorta. I can't tell if the speed improvements are from the Rust front end or the back end format changes, but it's a lot faster than Vorta/Borg and certainly way faster than Kopia on restore.
There's a reddit announcement with more info. Borg is single threaded and this uses all cores, so that may be one of the reasons for the speed increase: https://www.reddit.com/r/BorgBackup/comments/1ri02cx/introdu...
