Release Notes for Arq Backup Version 2.9

New Features

  • New scheduling option: back up every 'n' hours.

Fixed Bugs

  • Vastly improved handling of missing S3 objects. Instead of dropping backup records and starting over, Arq now rewrites the backup records and indicates where files are missing in S3.
  • Fixed the "stuck in restarting" problem.
  • Fixed an issue where invalid or out-of-date information in a cache file causes the backup to stop.
  • Changed budget enforcement to happen at the next backup time after budget enforcement start time is reached (instead of starting immediately).
  • Fixed an issue where the estimated upload size was much too large, usually after installing an Arq update with an updated internal data format.
  • Fixed an issue where the backup would fail on a transient 'connection refused' error.
  • Fixed an issue with stale file data which caused an error related to an "AgentMutablePackEntry" with the wrong size.

  • Release Notes for Arq Backup Version 2.8.2

    Fixed Bugs

    Signed the app with our new Mountain Lion-compatible "Developer ID" identity to prevent errors when attempting to download and launch Arq on Mountain Lion.

    Release Notes for Arq Backup Version 2.8

    New Features

    • Added "answer file" support. Arq can now be configured using an answer file as described in the Arq manual.

    Fixed Bugs

    • Catch "bad file descriptor" errors (which seem to happen often when Arq tries to back up Apple "receipt" files) and warn about those files instead of failing the entire backup.
    • Provide the filename in the error message when a read error occurs.
    • Fixed an issue where some symlinks with unusual names weren't being backed up correctly.
    • Catch "address not available" network errors and retry.

    Fixed Bugs

    • Fixed an issue where changes to extended attributes weren't being backed up if the file data didn't change as well.
    • Fixed a crash that happens after transient (usually network) errors occur during restoring.
    • Fixed an issue where unencrypted content-type info was being written to S3.

    Other Improvements

    • Reduced the number of filesystem calls to improve backup performance and reduce load.

    Please Note: Arq versions 2.6.3 and 2.6.4 stored invalid backups. If you have used either of those versions, when you update to version 2.7 (or later) Arq will check for old data that may have this problem, and will prompt you to drop backups since March 7 if you think you had version 2.6.3 or 2.6.4 previously installed.

    The full details of the bug are in this blog post.

    • Log the error code and description when SecKeychainItemCreateFromContent fails (rare).

When it's done backing up it savesthe last pack in S3 too. The next time it backs up, it starts with thatlast pack and adds to it until it reaches 10MB, at which point it replacesthat last pack with the new full-size pack. The restore process was tryingto read from the pack that the backup process deleted (replaced with adifferent pack). If you restarted Arq and tried restoring again, it foundthe new pack and worked fine.

Backed-up files will not be re-uploaded. Sorry aboutthis! I aim to never do this sort of thing again, but I decided it wassafer to do this (partially because it's still beta) than to add lots ofcomplex code to read the old/broken objects as well as the new/fixed ones.If you have questions please send me mail atstefan@haystacksoftware.com.
