Changelog

2.1.1 (2016-01-15)

  • Fix logging bugs.
  • Shut down daemon loop cleanly on signal reception.

2.1 (2016-01-08)

  • Add optional regex filter to the jobs command in the telnet shell.
  • Provide list of failed jobs in check output, not only the total number.
  • Add status-interval, telnet-addrs, and telnet-port configuration options.
  • Automatically recover from missing/damaged last or last.rev symlinks (#19532).
  • Use {BASE_DIR}/.lock as daemon lock file instead of the status file.
  • Usability improvements: count jobs, more informative log output.
  • Support restoring to block special files like LVM volumes (#31).

2.0 (2015-11-06)

  • backy now accepts a -l option to specify a log file. If no such option is given, it logs to stdout.
  • Add backy find -r REVISION subcommand to query image paths from shell scripts.
  • Fix monitoring bug where partially written images made the check go green (#30).
  • Greatly improve error handling and detection of failed jobs.
  • Performance improvement: turn off line buffering in bulk file operations (#20).
  • The scheduler reports child failures (exit status > 0) now in the main log.
  • Fix fallocate() behaviour on 32 bit systems.
  • The flyingcircus source type now requires 3 arguments: vm, pool, image.

2.0b3 (2015-10-02)

  • Improve telnet console.
  • Provide Nix build script.
  • Generate requirements.txt automatically from buildout’s versions.cfg.

2.0b2 (2015-09-15)

  • Introduce scheduler and rework the main backup command. The backy command is now only responsible for dealing with individual backups.

    It does no longer care about scheduling.

    A new daemon and a central configuration file is responsible for that now. However, it simply calls out to the existing backy command so we can still manually interact with the system even if we do not use the daemon.

  • Add consul integration for backing up Flying Circus root disk images with clean snapshots (by asking fc.qemu to use fs-freeze before preparing a Ceph snapshot).

  • Switch to shorter UUIDs. Existing files with old UUIDs are compatible.

  • Turn the configuration format into YAML. Old files are still compatible. New configs will be generated as YAML.

  • Performance: defrag all new files automatically to avoid btrfs degrading extent performance. It appears this doesn’t completely duplicate all CoW data. Will have to monitor this in the future.

2.0b1 (2014-07-07)

  • Clean up docs.
  • Add classifiers in setup.py.
  • More or less complete rewrite expecting a copy-on-write filesystem as the target.
  • Flexible backup scheduling using free-form tags.
  • Compatible with Python 3.2-3.4.
  • Initial open source import as provided by Daniel Kraft (D9T).
