Backups can play an instrumental role in case of disaster recovery and also have the potential to make a company immune to data loss. The process of backing up information can be lengthy and this is where the use of storage snapshot technology attains its prominence. With the presence of snapshot technology, firms can restore only what they need, instead of taking time to recover all the information. That means, snapshots keep a track of changes happening to the stored data from time to time and thus it shortens the recovery time to incredible levels.
In a recent survey carried out by Nimble, 1600 respondents participated on the subject of backup and storage technology. Around 60% of them admitted that snapshot storage adoption is growing and most among the users are large enterprises which are relying on the snapshot tool as a part of data protection strategy.
The exact requirement for the creation of snapshot will vary among companies, but most storage engineers endorse on having a short time between each snapshot for maximum protection. Some also strongly support on customizing the storage system take snapshots for every 15 minutes in order to protect the data in an effective way. They also have an opinion that the chosen backup technology must also be able to retain those snapshots in a cost-effective way.
Accordingly, targeting these companies StoneFly, Inc., offers the snapshot technology feature in all its iSCSI storage appliances. Thus, with the help of this feature the IP SAN appliances offered by this Silicon Valley based company succeed in offering advanced data protection, essential for mission critical businesses.
The other point which has to be lined out is the usage of separate recovery appliance for disaster recovery purpose which may or may not be geographically separated. Some small businesses depend on cloud service providers for their backup needs and offer pricing that is targeted at smaller companies. In certain situations, small businesses will get the benefit of having their disaster recovery site separated from their headquarters in order to ensure that they can recover applications and data quickly. But when data security and integrity come into focus, more organizations will prefer on having their backed up data on site, rather in the cloud.
This is where the importance of having a backup appliance on-premise gains its value. Small and Medium scale businesses feel more secure in having their data backed up on their premises or at a place which is geographically separated and is conducive for disaster recovery.
Finally, on a conclusion note, the protocol is to first figure out what your business requirements are for recovery point and recovery time and then go for storage enriched with snapshot technology which fulfills all your recovery and business continuity objectives.
