  • 1. Setting up data redundancy on DSS V6 with Asynchronous Data Replication and local BackupSoftware Version: DSS ver. 6.00 up50Presentation updated: October 2010
  • 2. Local Data Redundancy with DSS SAMPLE CONFIGURATIONLocal Data Redundancy as described in this document does not fulfill professionalbackup requirements, but is strongly recommended if you are using no backup at all.Experience shows that most data loss incidents can be protected with this simple andinexpensive solution. Local Data Redundacy as explained within this document requiresa single NAS device with two RAID Arrays within the system.Local Data Redundancy uses two of the features built into the Open-E DSS V6:•Local Backup with Restore•Data Replication An example configuration:•First Array RAID is for live data on volume group DATA (vg00)•Second Array RAID is for backup and replications as volume group BACKUP (vg01)Setup Backup and Data Replication:  Backup schedule is set every day with a 6 week retention time for “DATA” share  Scheduled Data Replication is set for an hourly interval for “DATA” share www.open-e.com 2
  • 3. Local Data Redundancy with DSSLocal Data Redundancy  Recommended Resources • Hardware  x86 compatible  RAID Controller 1  RAID Controller 2 (optional, single RAID controller can manage 2 RAID arrays as well)  HDD‘s  Network Interface Cards • Software  Single Open-E DSS V6  Benefits • Low cost solution • Ensures local data availability  Disadvantages • In case of total disaster, such as fire or flood, data and the backup could be lost www.open-e.com 3
  • 4. Local Data Redundancy with DSSTo Set up Local Data Redundancy, Perform the Following Steps: 1. Configure Hardware 2. Configure the Local Backup 3. Create the Restore from Backup 4. Configure the Data Replication www.open-e.com 4
