Comparison rustic vs. restic

Improvements implemented in rustic:

Allows using cold storage (e.g. AWS Glacier) repos which are only read in the restore command + supports warm-up
All operations are completely lock-free as rustic supports two-phase-pruning (prune option instant-delete is available)
Supports configuration in a config file (example config files)
Huge decrease in memory requirement
Already faster than restic for most operations (but not yet fully speed optimized)
Cleaner concept of logging output; possibility to write logs to a log file
rustic repair command allows to repair some kinds of broken repositories
backup command can use .gitignore files
restore uses existing files; also option --delete available
Snapshots save much more information, available in snapshots command
Integrates the Rhai script language for snapshot filtering
Allows to save repository options in the repository config file via the command config
New command merge
New command repo-info
check command checks and uses cache; option --trust-cache is available
Option prune --fast-repack for faster repacking
Syntax <SNAPSHOT>[:PATH] is available for many commands
