Hi Aldevinas,
What you are seeing in your log is only debug information. 'Tag' is a specific part of the text backup that is inspected and imported according to any import routines.
eg. 2021-03-12 14:19:58 (-1) done importing tag "company4" starting with tag "Demo", 315081 RLinks in the database
In this particular case 'company4' is the 4th version of companies block. If the database is really importing a text backup, and the user did not ask for or want that, something else is wrong, a bit later there will be messages explaining if it really imported or only inspected.
You are worried about tag 'Demo' and we are aware of several tags that are bugs in the debug log and these tags are not necessarily imported. This is because we do NOT import unrecognised tags - they are ignored.
Good example of this is: 2021-03-12 14:19:58 (-1) done importing tag "1" starting with tag "", 315081 RLinks in the database
There is no tag '1' but this still works because we ignore it.
There is nothing to worry about unless you are seeing data corruption or other problems and in such case please report a bug and we will have a look at it.
Best Regards,
David D.
