"Shard XX removed during backup"

Hi. I am running Influxdb 2.1 on a pi4 in docker. I am trying to create a backup via command line
Influx CLI 2.2.1 (git: 31ac783) build_date: 2021-11-09T21:24:22Z.
The command is:

docker exec influx influx backup \
[path here] \
-t [token here] 

then the backup starts, but 18 shards are “removed during backup” - and missing afterwards in the backup.

Is that inteded behaviour? How can I fix that? If tried this over several days, after rebooting and while stopping the other docker tasks (that access the database) - its always the (same?) 18 shards that fail.

Any help is appreciated. Thankyou

If anybody has a clue about it, I would still like to hear it. I have now 78 shards and still the same error :frowning:

Recovery of the data failed :frowning:
