It’s very strange because I use wevdav to store files (Yandex.Disk). But it’s strange twice when I restored only one file from backup. I didn’t see any error. Also I did md5 of all files before. The md5 from old disk and restored only one is the same.

BTW, I don’t understand - what the file hash algorithm because my returns another value.

Also I restored another backup to new drive from old. I have no errors, but my test shows me than one file didn’t restored. Later I restored only this file successfully.

I saw that one file was absent by check md5 file of all files from old drive.

I’m disappointed with D2.

Could I create issue with these?

BTW, I didn’t lost any data. I see two problems with restore.
