I’m currently managing a massive dataset sitting in OneDrive (several terabytes across multiple accounts/folders), and I’m looking for solid recommendations for backup and restore software.
Syncing everything locally using the standard OneDrive client isn't cut out for data at this scale—API throttling, sync loops, missing metadata, and local storage limits become a major issue.
I’m looking for a solution (open-source or enterprise/dedicated software) that satisfies these key requirements:
What I need:
- Scalability for Large Volume: Handles multi-TB transfers reliably without choking, crashing mid-process, or timing out.
- Incremental/Delta Backup: Only backs up new or modified files after the initial full dump to save bandwidth and time.
- Integrity & Metadata Preservation: Preserves folder structures, creation/modification timestamps, and file attributes.
- Throttling Resistance: Uses modern OAuth authentication and handles Microsoft Graph API rate limits gracefully (with auto-retry mechanisms).
- Flexible Destination Options: Ability to back up to local storage (NAS/SAN/HDD) or secondary cloud targets (S3, local servers, secondary M365 accounts).
Are command-line options like Rclone reliable enough for multi-TB restores when non-technical users might need file recovery, or do you prefer GUI-based dedicated backup/migration suites (like Shoviv OneDrive Migrator, or Cloudberry/MSP360)?
How do you handle restoring specific point-in-time snapshots when dealing with massive file counts?
Would love to hear what has worked (and what failed) for those managing large volumes of data on Microsoft 365 / OneDrive!
Thanks in advance!
