@patrickwilliams2345 Thanks for reporting.
If possible, could you please describe your setup in detail?
Which OS?
Which backend?
What is softraid referring to? (in the path)
Where exactly is the repository located?

Also, if you run vykar in a terminal, does is show useful error messages?
For verbose mode also try vykar -v backup
for even more messages try vykar -vv backup

I've had this twice with the new version using macOs 26.4 (released today) and Backblaze B2. Sadly, I'm not yet getting the error anymore, but will keep running with -vv and tee'ing the logs.

Hopefully @patrickwilliams2345 has some useful logging.

Thanks for the details. os error 60 is macOS's ETIMEDOUT — the operating system itself is reporting that an I/O operation didn't complete in time. This isn't an error generated by vykar; we're surfacing what the OS returns.

Since your repository is on attached SoftRAID storage, this most likely points to the external volume being temporarily unreachable during the backup — common causes include:

• Drive going to sleep mid-operation (System Settings > Energy > disable "Put hard disks to sleep when possible")
• Cable/enclosure intermittent connection issues
• SoftRAID driver compatibility with macOS Tahoe
• A degraded RAID array with slow/failing member disk

A few things to try:

1. Run vykar -vv backup from a terminal to get the full error trace — it will show exactly which file or operation triggered the timeout
2. Check Console.app for disk I/O errors around the same timestamp
3. Verify the SoftRAID volume health in the SoftRAID utility

@talios For B2, timeouts are transient network errors — vykar does retry these automatically (up to 3 attempts with backoff). If you're still seeing failures after retries, -vv output would help confirm whether retries are being exhausted.
