Hi Adam, Solr's backup functionality integrated into the /replication handler is relatively simple - it just iterates over index files and copies them to the requested location. The only time that replication handler backup delete files is when the backup fails and Solr tries to clean up after itself.
Do the Solr logs contain any errors relevant to the backup? In many cases this'll look like a message that starts with "Exception while creating snapshot", though not always. Does the "command=details" replication command (https://solr.apache.org/guide/8_6/making-and-restoring-backups.html#backup-status) give any details about the final state of the backup attempt? Good luck debugging; please let us know what you find. Best, Jason On Thu, Mar 18, 2021 at 6:50 AM adamw <ad...@media-press.tv.invalid> wrote: > > I have a problem while performing a backup.
