Cloud Backup vs Traditional Backup: Which Is Safer?
Cloud storage backup is a strategy for backing up data that involves removing data offsite to a managed service provider for protection. It can either replace or complement on-premise backups. Many enterprises have stuck by their tried and tested methods of backing up their data (and servers) to an on-site, tangible hard drive. With the threat of cyber-attacks and malware ever present, the need for off-site storage has increased exponentially.
What Are The Advantages and Disadvantages of Cloud Based Backup?
You broaden your storage capacity with offsite storage.
Backing up your data to a backup-centre other than your premises eliminates the threat of disasters such as fire and theft impacting the safety of your backed-up data.
- Increased security
All backups are encrypted before leaving your offices which means that your data stored with is 100% secure – even if stolen.
- It is a far cheaper solution
Cloud computing allows business to consume more IT while keeping costs down. Business now has a cost-effective reason to implement proper backup – there is no need to spend money on physical backups, only the fee for cloud-based storage (which is usually cheaper, the more data you add).
- Automated backups ensure nothing is left to chance
By removing the human element from your backups you can rest assured that backups are taken care of 365 days a year.
- The biggest possible threat is cloud-based malware; while this threat is present everywhere, the added step of encrypting your data will safeguard you from such an event.
What Methods are used in Cloud Backups?
Physical or cloud environment to cloud mirroring
“The cloud is elastic, so you can deploy your disaster recovery plan in a number of ways. You can have two environments: one physical and one cloud. Or, you can have two clouds that are live and replicate between them. Special software replicates between two environments — a source and target. The software ensures the target environment will match the source environment. In this scenario, you achieve high availability, rapid recovery, minimal data loss, and the ability to scale with your needs without all the capital expenditures on hardware and software. You will still have to license the dual environments, as well as the replication software. However, it is a robust option, especially for highly transactional applications.”
“If you need more than daily backups to ensure business continuity and compliance, Peak 10’s Recovery Cloud is a great option. Unlike an active/active scenario, use of the Recovery Cloud means you won’t have to pay for licensing of software except in a disaster. Plus, there is no expensive hardware to buy and maintain, downtime is minimal and there is minimal data loss. Your data can be in an on-premise data center, colocated in a Peak 10 data center, or in a Peak 10 cloud environment. With the Recovery Cloud, your data is continuously protected as it changes. This helps ensure a rapid recovery with minimal data loss. Because the Recovery Cloud is a fully managed service, our staff will begin spinning up your virtual machines (VMs) to the cloud within an hour of a disaster declaration and will have you up and running in four hours.
While the Recovery Cloud may be more expensive than just doing a traditional backup, it delivers a recovery solution that protects, recovers, reports and automates your IT disaster recovery plan.”
What Are The Advantages and Disadvantages of On-Site/ Traditional Backup?
Traditional data backup involves creating one (or more) copies of an original file to be accessed and / or used should the original file become lost or corrupted.
Some benefits are the ability to instantly recover data (if the files are accessible form a corrupted hard drive) and being able to manually perform backups. This may not be considered an advantage by many, as the human element sometimes fails us in being “on the ball” in terms of routine backups. The threats of backing up your data the traditional way alone far outweigh the benefits, so we would always suggest the addition of cloud-based backup to ensure you are at no stage compromised in your data recovery efforts.
What Methods are used in Traditional Backups?
Daily data backup to tape or disk
“Daily data backups are the mainstay of disaster recovery. It’s a scheduled event that is highly effective in ensuring you have all of your data, and it is relatively inexpensive to do. However, you will need to consider the potential loss of data between the last backup and the event that forced you to failover. Can you afford to lose that data? Backups can be slow and sometimes difficult to restore, because the restoration environment must exactly match the backed up environment. With this method, you’re managing your own failover/failback. Do you have sufficient IT resources to rebuild your network, provision hardware, stage the recovery platform, and recover data before downtime affects your business?”
Off-site mirrored physical servers
“Another option is the use of mirrored servers. This method is great in terms of recovery time, because there’s no restoration required. Mirroring is done in real time so transactions on system A are immediately sent to system B. There is very little difference between production and your mirrored environment. In fact, administrators generally get to do everything twice: purchase, patch, upgrade, and perform other system maintenance procedures that can require extensive tracking and change management. The downside of a mirrored server strategy is the cost, which can be formidable (2x – 5x the cost of the production systems). Purchasing and maintaining identical equipment, substantial connectivity between systems, space and cooling for all the hardware, advanced mirroring software and specialized technical staff are prohibitively expensive for many companies. If you are contemplating expansion of your business, this may prove burdensome to scale.”
