Hi everyone,
Quick warning: there are reports that the latest Windows security update is breaking or disrupting several third-party backup applications.
VaultSync is currently being tested against this. I do not yet have enough information to say that VaultSync is affected, but because this seems to involve backup software more broadly, I want to treat it as urgent.
If you use VaultSync on Windows, your reports are extremely valuable right now.
Please let me know if you notice:
- failed backups
- permission/access errors
- unreachable destinations
- restore problems
- verification errors
- crashes
- anything that started after the latest Windows update
Useful details:
- Windows version
- VaultSync version
- destination type: local, USB, NAS, SMB, etc.
- error message or log snippet
- whether the issue started after installing the latest Windows update
Until this is clearer, please verify that your backups are still completing correctly and consider testing a small restore.
I will continue testing and post updates as soon as I have confirmed information.
Update:
Good news: from everything I can see so far, VaultSync does not seem to be affected by this Windows backup-tool issue.
The reports going around appear to be related to backup tools that depend on Windows VSS snapshots or image-mount drivers. VaultSync does not use that kind of backup path. On Windows, VaultSync is mostly working through normal file copy/sync/archive flows, such as robocopy/rsync, managed file copy, ZIP/archive snapshots, and optional network-share handling.
I tested the parts that matter most:
- snapshot / sync / verify passed
- writing to the backup destination worked
- targeted backup into the destination completed and verified correctly
So for now, VaultSync looks safe from this specific issue.
I’ll keep watching this and testing more, but the current state is positive.
If anyone sees different behavior on their machine, please still report it. Real-world reports are always useful, especially with your Windows version, VaultSync version, destination type, and any error/log message.
