could not link file in wal restore lines

Hi,

I'm testing pgbackrest restore.

It works well, but in the pg logs I get the following lines:

could not link file "pg_wal/000000010000015600000098" to
"pg_wal/00000001000001570000006E": File exists

In total, I get 18 lines of "could not link file" and 932 lines of
"restored log file" lines.

At the end it finishes with:

redo done at 15A/A001710
last completed transaction was at log time 2022-07-15 19:41:05.175573+00
restored log file "000000030000015A0000000A" from archive
selected new timeline ID: 4
archive recovery complete
restored log file "00000003.history" from archive
database system is ready to accept connections

Before going in production, I wanted to ask, if this is correct like this?
I mean are those "could not link file" lines anything to worry about?

Thanks and regards,
Zsolt
