Restic 0.19.0 Released

We are happy to announce the release of restic 0.19.0!

As with previous releases, this one contains many different enhancements, some optimizations as well as a few bugfixes. We are grateful to all the contributors who spent their time and effort to help improve restic yet another time - thank you! Also a huge thanks to everyone in the restic community, who answers technical and non-technical questions tirelessly for both existing and new users - this is very helpful and much appreciated.

Some of the most important changes in this release are:

• Restic now supports the zstd compression modes fastest and better, allowing for more tailored choice of compression.
• Loading the index for a large repository is now significantly faster, and the mount command loads new index files on demand.
• The check, copy, diff and stats commands now use less memory when handling large snapshots.
• The restore command now supports restoring file ownership on UNIX systems by user and group name with the --ownership-by-name option.
• The backup command now supports --exclude-cloud-files (previously only available on Windows) on supported macOS versions to skip cloud-only files.

Other notable changes include:

• API transaction costs for files up to 256 MiB are reduced by about half in the Azure backend.
• The copy command now copies multiple snapshots together so that small pack files are avoided where possible.
• The backup command no longer applies exclude rules to paths given on the command line itself (excludes still apply to contents within those paths).
• The check command now supports snapshot filters (--tag, --host, --path, or explicit snapshot IDs).
• The rewrite command now supports include filters (--include, --include-file, --iinclude, --iinclude-file).
• Serving files from a Windows backup in a mounted restic repository using Samba is now possible on a POSIX system.
• Access Control Entry inheritance on Windows is now restored correctly.
• The official restic Docker image now supports nice and ionice scheduling hints.
• Exit codes have been improved for certain situations and signals, improving scripting reliability.
• Several UX improvements have been made in the CLI and restic’s output.
