![]() The physical data set is protected within the node and across nodes within the same logical datacenter. A SimpliVity backup of a VM is a full, completely independent (independent is the keyword here and one which will be repeated often throughout this post), copy of the references to data stored on disk (the VM’s metadata – this metadata is an abstraction of the physical dataset – again unlearn what you have learned). Snapshots are deltas of the original and maintain a dependency on the original, when the original VM is deleted the snapshots are useless for recovery. A snapshot has some dependency on the original. A deeper dive into the SVTFS and how it deduplicates and protects data can be found in Ron Singler’s ( post Deduplication, You Must Unlearn What you Have Learned (Definitely worth a read).įirst things first, SimpliVity backups are NOT snapshots. The SimpliVity Data Virtualization Platform (DVP) which is comprised of the SimpliVity File System and Object Store (SVTFS) enables the efficient storage and protection of data by deduplicating, compressing, and optimizing all data, at inception, once and forever, across all tiers, and across all sites. So what happens when we take a SimpliVity backup and how can we claim to follow the 3-2-1 strategy? Backup policies are VM-centric, this allows for a policy to be applied directly to a VM based on that VM’s RPO. If we want to replicate a monthly backup to another datacenter which we retain for 7 years, just create another rule. So if we also wanted to take a backup every Sunday which we retain for 1 year, we can simply create another rule. Each SimpliVity backup policy can be configured with up to 16 rules. In this policy there are two rules: the first rule creates a backup every 4 hours, retains the backup for 7 days, and stores the backup in the Raleigh Datacenter the second rule creates a backup every 4 hours, retains the backup for 14 days, and stores the backup in the Tampa Datacenter. ![]() Here is an example of a simple SimpliVity backup policy: We are able to easily provide a data protection solution which aligns with a traditional and proven 3-2-1 Backup Strategy: 3 copies, 2 independent media sets, and 1 off-site copy. The backup policy engine and the backup catalog are part of the SimpliVity DVP. The SimpliVity Data Virtualization Platform (DVP) provides native data protection including policy based backup, replication, and recovery. ![]()
