It is recommended that you have separate, dedicated storage for the backup system regardless of the storage media (SAN, tape, attached magnetic device, etc.). Hyland Software, Inc. recommends RAID 5 configuration for hardware fault tolerance. Hyland Software, Inc. also recommends keeping between one week and one month's worth of backups available, based on storage capabilities and recovery requirements.
It is strongly recommended that you store all database backup files in a different location than the production database. If the database backup is stored in the same location as the production database, the entire database will be lost in the event of a hardware failure. Additionally, it is recommended that you restore a copy of the database on a regular basis to validate the integrity of the backup.
