Hi.
We have a database (Derby) and a Lucene index. We want to perform backups without stopping the database (i.e. live backup).

When I want to perform the backup of the database I simple call Derby's internal backup function which do it safely for me. But how to backup the index if I want to copy the FS index to a zip file? I used to copy the index directory manually but this does not not work if there is some indexing in progress at the same time. And of course the database backup and index backup should be performed within one transaction.

Thank you

Hi,

afaik there is no good way of doing this. It relates to this jira issue - HSEARCH-816. Once it is possible to configure the IndexDeletionPolicy, a SnapshotDeletionPolicy could be used to create a backup. See also http://stackoverflow.com/questions/5897 ... dex-backup

I created an issue for that - HSEARCH-1006
