Release Notes for Arq Backup Version 7.31.0.0

Aug 15, 2024

Release Notes for Arq Backup Version 7.30.3.0

Aug 1, 2024

Changes

• If you add a mount-point type reparse point as a folder to be backed up in your backup plan, Arq will traverse the reparse point and back up the contents of that volume.

Release Notes for Arq Backup Version 7.27.8.0

May 3, 2024

Fixed Issues

• Fixed an issue where a file that was "Deleted/Kept" (because the backup plan's settings included keeping deleted files in subseequent backup records) which subsequently reappeared was still shown as "Deleted/Kept".

Release Notes for Arq Backup Version 7.27.7.0

March 29, 2024

Fixed Issues

• Fixed an issue where Arq would show a Google error 'unauthorized_client' instead of prompting to grant access.
• When launched, Arq attempts to check whether OAuth tokens are valid, and prompts to grant access for any token that isn't valid.
• Arq checks whether the authorized Google Cloud Storage OAuth token actually has access to the data, not just that it's a valid token, and prompts to grant access if not.

Release Notes for Arq Backup Version 7.27.3.0

March 27, 2024

Fixed Issues

September 27, 2023

Changes

Release Notes for Arq Backup Version 7.24.2.0

September 25, 2023

Changes

• Added a workaround for Storj's S3 incompatibility (returning a 429 HTTP status code instead of 503 as S3 does).
• Removed the "thinning" function from backup plans. Too many people found backup records were permanently deleted that they weren't expecting to be deleted, and that's a really bad user experience, so we felt it was best to remove the function. As an alternative to limit the amount of storage used by your backup plan, edit the plan, click the Retention tab, check 'Limit storage used' and enter a value.
• Changed "Delete..." button label to "Delete Backup Record..." to make it clearer what the button does; also added a confirmation dialog with a reminder that the action is permanent and cannot be undone.

• Fixed an issue which caused a crash in restore-only mode.

April 26, 2023

Improvements

• Added Import and Export buttons for a backup plan's file selections.
• Added support for new AWS regions.
• Added "Use Dual-Stack AWS Endpoint" checkbox for AWS storage locations.
• When restoring a folder containing "deleted" items (because "keep deleted files in subsequent backup records" option was checked in the backup plan, don't restore those "deleted" items. "Deleted" items can still be individually restored.
• When adding a B2 storage location and user chooses an existing bucket, show an error if bucket's lifecycle policy isn't 'keep only last version'.
• When loading backup sets, if a backup set is missing items, show it anyway (with an error message) so that the user can select it and delete it.

Fixed Issues

October 17, 2022

Updates

• Added a workaround to support S3-compatible storage locations (e2, Minio) with object lock which return non-standard error codes when attempting to delete a locked object, causing Arq to report an error for an action which isn't actually an error.

Release Notes for Arq Backup Version 7.19.12.0

September 6, 2022

Updates

• Updated Google OAuth authorization process to comply with Google's policy change deprecating the OAuth "out-of-band" flow.
• Store the key derived from the "app password" instead of the actual app password. This protects against malware running as root potentially stealing the app password, which a user might reuse elsewhere.
• Return a better error message from B2 when a file is not found instead of B2's generic "file with such name does not exist" message.

Release Notes for Arq Backup Version 7.19.10.0

September 6, 2022

Fixed Issues>

• When backing up to an SFTP server, retry up to 5 times rather than retrying for up to 60 seconds, to ensure that Arq retries in the case of a timeout.
• Instead of storing the backup plan encryption password (accessible only by root), store the encryption key derived from it (accessible only by root). This protects against malware running as root potentially stealing the encryption password, which a user might reuse elsewhere, thus potentially giving an attacker access to data beyond that legitimately needed for Arq's normal operation. This addresses CVE-2022-36617 filed by Sam Haskins.

Release Notes for Arq Backup Version 7.18.0.0

March 29, 2022

Fixed Issues

Arq 7.18 will accept all Arq 7 licenses regardless of updates-end-date in order to work around this issue for people who experienced it.

Release Notes for Arq Backup Version 7.12.0.0

December 17, 2021

Changes

• Changed Arq's behavior regarding unknown objects found when adopting backup sets (or upgrading from Arq 5). On first backup after adopting a backup set, Arq will initialize its database from existing data as much as possible; it will reuse objects as much as it can and leav the remaining objects alone. The "Remove Unreferenced Data" function will delete all unreferenced data, including objects found during initialization that weren't referenced by any backup record that Arq was successfully able to read during initialization. This resolves the scenario where, with Arq 5, the user may have deleted backup records but not executed Arq 5's "Remove Unreferenced Data" function.
• Retry on HTTP 408 errors.
• Changed the retention behavior: When applying retention rules after backup, Arq now writes to the activity log every backup record date/time and whether it was kept or deleted.

Fixed Issues

• Fixed a bug that could cause a crash when clicking "Create Backup Plan" with no storage locations configured (which causes the add-storage-location dialog to appear) and then clicking Cancel on the add-storage-location dialog.
• Fixed an issue where Arq could crash if the Restore button is clicked before a storage location has been selected.
• Fixed an issue that could cause a null-reference exception when browsing S3 data in a versioned bucket where versioning has been turned off and later turned on, resulting in some objects with 'null' as the version ID.
• Fixed an issue where script arguments weren't being passed correctly when executing postflight scripts.
• Fixed tab navigation issues in the edit-backup-plan window.

Release Notes for Arq Backup Version 7.11.0.0

• Check for .NET version 4.7.2 or later, and write to event log if it's not available.
• Fixed an issue where no-backups-after-n-days alerts weren't being shown.
• Removed a workaround that was causing Arq to retry on erroneous Amazon Drive 400 errors (which Amazon Drive seems to have stopped sending).

Release Notes for Arq Backup Version 7.9.6.0

November 5, 2021

Improvements

Fixed Issues

• Added a workaround for unexpected error responses from Microsoft Graph API (OneDrive/SharePoint).
• Fixed an issue where network-transfer-rate limit wasn't being used when backing up to SFTP.
• Fixed an issue where deleted/kept files weren't properly being marked as deleted/kept when the "keep deleted files in subsequent backup records" option was enabled in the backup plan.

Official Arq 7 Release

More power, more security, more storage savings.

Perfect backups

Arq uses Windows Volume Shadow Copy Service to create perfectly consistent backups of your files every time.

If you're modifying your files as they're being backed up, it won't affect the backups.

More power

• Run multiple backup jobs in parallel
• Scans and uploads files in parallel for faster throughput
• Only scans changed files/directories after the initial backup (uses filesystem events to detect changes on macOS and Windows)
• New data format which eliminates the need for reading metadata before browsing/downloading from backups.
• You can limit the scheduled backups to certain days of the week
• You can limit transfer rate to certain times of the day at certain days of the week
• Powerful new rules for selecting which files and folders are included and excluded from backup
• Time-based retention rules in addition to budget-based rules
• Optionally keep deleted files in subsequent backups for easy locating of deleted files
• Get alerts when no backups have occurred for days

More secure

• Set a password on Arq 7 to prevent others from opening Arq and deleting backups.
• Uses SHA256 for checksums instead of SHA1.

More storage savings

• Arq 7 can back up to AWS Glacier Deep Archive. Store your backups there for $0.99/TB per month.
• Arq 7 can back up to Google Cloud Archive. Store your backups there for $1.230/TB per month with instant access to backups..

New Arq Premium subscription option

All the features of Arq 7 plus:

• 1 TB storage included

• Simpler configuration
• Secure web access to your backups
• $5.99/month (extra storage billed at $.00599/GB per month)

• Destination-agnostic, portable data format that's open and documented
• Progress bars showing percent complete
• Wake for backup
• More informative SMTP test results — full SMTP connection log when an error occurs
