What does that mean? During weekend we have not configured any backups to datastore pbs-backup. Only a sync job for to a local remote datastore (removable usb disk) which did successfully get executed.

Is it possible that these are backups that were pruned from pbs-backup datastore thus cannot be verified on the removable datastore?

Talking of prune, I checked and realized that the configured prunge and gc settings are gone, and I don't know why.

sync basically pulls the metadata and chunks via the download API path, so likely those log entries were just the sync? that they end with the transport message can happen when the client closes the connection before the server expected too.
 
Hm, well the client and the server is on the same machine, as I configured a remote -> localhost as workaround to be able to sync the datastore content to an offline medium. So am I supposed to just ignore those kind of messages, or can I do something to make them disapear?
 
yes, you can ignore those messages if the client-side (sync/backup/restore) does not complain/show any errors.
 
Just to clarify - you mean as the following message which appears just after the last error message indicates the the sync finished successfully, then I can ignore it, right?:

yes. basically the client (=sync in this case) is done, closes the connection, and the server only sees "connection is closed" and logs the warning.
 
Is it still relevant that error in PBS Tasks after "Sync Job" on the same machine can be ignored ?
