4 years ago As far as I can tell from your report you have not copied over the datastore. Exports only contain metadata information needed to create a restore / nbd mount from a backup. If you want to restore from another host, you must make the data backend available to the other host. Either by rsyncing it over or by give nfs / something else mount to the other host. The usecase here is that we use an s3 store as data backend and create backy2 metadata exports and store those too in a s3 bucket.

hi. Two backy2 servers are up and running. Backupdata exported from server 1. Error occurred while importing and restoring server 2. How do I fix it? DB is using postgresql.
