Fixed long-term memory usage issues in Arq Agent.
Log the error code and description when SecKeychainItemCreateFromContent fails (rare).
Fixed an issue that was causing occasional temporary "not found" errors on restore: When Arq backs up, it stores small files in "packs". When a pack reaches 10MB, Arq saves it to S3. When it's done backing up it saves the last pack in S3 too. The next time it backs up, it starts with that last pack and adds to it until it reaches 10MB, at which point it replaces that last pack with the new full-size pack. The restore process was trying to read from the pack that the backup process deleted (replaced with a different pack). If you restarted Arq and tried restoring again, it found the new pack and worked fine.

Release Notes for Arq Backup Beta Version 1.1.0

(Released Wed Jan 27 09:38:16 EST 2010)

New version: 1.1

Version 1.1 (still in beta) is dramatically faster when backing up many small files. It combines small files into larger files before uploading to S3, resulting in up to 60x faster backups. Restores are similarly improved.

Feature Additions

Dramatic speed improvements.

Bug Fixes

Immediate retry of S3 PUT request on "broken pipe" errors (instead of restarting the backup of the folder).
When adding a folder that is a "mount point", automatically add "/.Trashes", "/.Spotlight-V100" and "/.fseventsd" to excludes.
Removed confusing "minimum backup interval" preference from the GUI.
Fixed bugs around running Arq for multiple users on the same computer.

Release Notes for Arq Backup Beta Version 1.0.41

Bug Fixes

Fixed byte-ordering issue in S3 objects (byte-ordering wasn't handled properly across Intel and PowerPC CPUs).
NOTE: All existing backup records in your S3 account will be ignored and a new initial backup will be created (in other words, backup history will start over). Backed-up files will not be re-uploaded. Sorry about this! I aim to never do this sort of thing again, but I decided it was safer to do this (partially because it's still beta) than to add lots of complex code to read the old/broken objects as well as the new/fixed ones. If you have questions please send me mail at stefan@haystacksoftware.com.
Fixed 3 memory leaks.
Removed 'maximum data file size' preference because it was confusing.
Many fixes around more robust handling of unexpected missing objects in S3 (e.g. if you delete objects from your S3 account that Arq was using).
Fixed an issue with bringing the app to the foreground while still in "setup assistant" mode.
