Incremental Backup
Backs up only those files that have been added to the database since the last backup was performed. Vertica supports incremental backups through file management utilities. Incremental backups are possible because Vertica never modifies data files. Vertica adds files to and deletes them from the database. Once you have created a full backup with vbr and any subsequent incremental backups, you can use vbr to do a full restore. There is no incremental restore facility.
