Backup Utility Download

See the Version 5 release notes for the full list of changes.

• Services with tables without a relationship class to a layer are now sent through the /export endpoint to improve backup consistency.
• Improved feature service retry logic.
• Logging and performance improvements.

• Item thumbnails now exported to ./Thumbnails within each item type folder.
• Item description JSON now exported to ./Descriptions within each item type folder.
• Portal /self JSON now exported to backup root as self.json.
• Users JSON now exported to backup root as users.json.
• Groups JSON now exported to backup root as groups.json.
• Vector tile style files (root.json) now exported to ./Styles/<item_id>.json within Vector Tile Service folder.
• Draft StoryMap and Web Experience items now exported instead of skipped.
• Improved logic for exclusion of faulty features to prevent total replica failure.

• Modified tile level assignment to improve tile layer export consistency.
• Improved export timeout and thread management and progress messaging.
• Improved management of long-running threads.

• Modified download URL for tile layer exports to accommodate external storage of ArcGIS Online-exported tile packages, retaining the third party token in those cases.
• Improved SSO, MFA, and browser authentication flow.
• Ability to add last_backup<timestamp> tags to items backed up (On-Demand versions only).

• Fixed issue where non-published forms and no-file items (e.g. some code attachments, report templates) showed as failed instead of indicating there was no file to be exported.
• Improved threadlock logic.
• Queued logging to prevent blocking I/O.

• Avoid in-memory buffering when probing /items/{id}/data on static items.
• Probes now stream headers only and static downloads stream to disk with resume support.
• Further improvements in memory management and performance.

• Improved token regeneration logic.
• Additional memory management improvements.
• Fixed issue with browser authentication on certain Portal for ArcGIS portals.
• Minor bugfixes and performance improvements.

• Fixed issue with Deep item query plus differential backup qualifying extra items on differential query.
• Fixed intermittent issue with exports of large or high-attachment feature services on Portal caused by a bug in ArcGIS API for Python.

• Fixed issue with corrupt feature exclusion when system-maintained feature ID field is not OBJECTID.
• Fixed item query failing under certain uncommon parameter combinations.
• Improved JSON handling when non-parsable characters are present in API response.

• Improved memory pressure management during simultaneous downloads.
• Improved replica zip check at runtime.
• Improved recursion and thread handling for large portals.
• Improved handling of system errors.
• Fixed bug with certain GeoJSON item exports returning empty arrays.
• Fixed bug with Portal returning 403 on layer checks under certain configurations.

• Improved memory management, especially for large or high item count portals. Download chunk sizes adjusted when system memory pressure is detected.
• Added dynamic connection pool sizing for more efficient HTTPS session management.

• Improved active download check at end of process, with additional static item retry for permissions errors.
• Added exponential backoff on deep query to accommodate API rate limits for large orgs.

• Additional static and JSON item retry when portal returns a permissions error, after generating a new token and re-instantiating the GIS object.
• Fixed issue with end-of-process feature service retries when API job limit is reached.
• Checks path lengths and notifies when items fail due to exceeding the Windows 260-character limit.

• Fixed issue with tile service and static item downloads when header returns incorrect file size or None.

• Added ability to specify multiple groups for backup.
• Improved connection pooling and retry logic in Requests session.
• Improved handling of corrupt or invalid static items.
• Fixed issue with inventory records when using Deep query option.

• Added concurrency to static item retries to speed up end of process.
• Fixed issue with failed static item export when item size returns 0 or None.
• Fixed issue with certain Portal exports failing due to header size mismatch.
