I am new to Restic but I already love it, so thanks for providing such a great tool!
Today, I have come across a bit a strange thing - “no parent snapshot found, will read all files”.
I have backup’ed this volume a few times and after the initial full full read/write, subsequent backups were always very quick because there were very few new files or file changes. So I was surprised to see a full read again. As far as I can remember, I am using exactly the same backup command because I have kept a log of it.
When the snapshot (with full read) was completed, I ran it straight again and this time, it worked perfectly, as in the past.
Did some more testing. I have 4 shares from the Synology mounted on the Windows 10 PC.
The “no parent snapshot found, will read all files” happened with 2 of them, the other 2 were fine, the parent snapshot was found.
That could be a possibility. The thing that speaks against is that when I ran the same command right after I had run it for the first time, I did work with with exactly the same syntax. Why would it run fine the second time?
