Kopia v0.7

Functional changes in v0.7.3

  • Improved restore performance (added parallelism)
  • Fixes for restoring symlinks
  • Added –force-color and –disable-color flags
  • Cleaned up console log output (removed timestamp by default, module) and refactored most output to use logger, so it can be controlled with flags. With this it’s now possible to have zero-output snapshot command suitable for crontab: kopia snapshot create --all --log-level=warning --no-progress

Functional changes in v0.7.2

  • Fixed retention tag application to incomplete snapshots, automatically apply at checkpoints. (#660)
  • repo: refresh indexes in the background every 15 minutes (#650)
  • Upgrade webdav client dependency to include bugfix for the race condition (#651)
  • b2: fixed handling of ‘no_such_file’ to indicate NOT_FOUND (#646)
  • cli: When listing directory that had errors, print error summary at the end. (#643)
  • Fixed empty object IDs in checkpoints (#649)
  • restore: improved user experience (#644)
  • Fixed few minor data races (#659)
  • Eliminated busy loop after snapshot failure (#658)

Compatibility Information

  • v0.7 release is compatible with repositories created with v0.6 and v0.5.
  • Due to splitter bug in previous releases (#595) repositories created using previous releases may not provide perfect deduplication for large files across multiple machines. Migrating the repository to v0.7 is recommended and will help reclaim the disk space.
