Xodus - Restore Environment / directory from Backup

This is how we backup Xodus:

PersistentEntityStore store = manager.getPersistentEntityStore(xodusRoot, appId);
final File backupFile = CompressBackupUtil.backup(store, new File(store.getLocation(), "backups"), null, true);

Using this ZIP file what is the safest way to restore the backup on a "production" or "live" server?

Solution

  • The only possible option is to unzip backup file and open a new PersistentEntityStore. You can keep open current instance of PersistentEntityStore until the backup is unzipped to a new location. Then you can open a new instance of PersistentEntityStore above the new location and switch atomically database load to the new instance.
