Package org.apache.solr.core.backup

Class BackupId

java.lang.Object

org.apache.solr.core.backup.BackupId

All Implemented Interfaces:

Comparable<BackupId>

public class BackupId
extends Object
implements Comparable<BackupId>

Represents the ID of a particular backup.

Backup IDs are used to track different backup points stored at the same backup-location under the same backup-name.

Incremental backups can have any non-negative integer as an ID, and ID's are expected to increase sequentially.

Traditional (now-deprecated) 'full-snapshot' backups only support a single backup point per name per location. So these all have the same ID value of TRADITIONAL_BACKUP
