Backup and Disaster Recovery– What’s Your Plan? Part 2
The UAE was fortunate to avoid disasters in the latest round of ransomware attacks, but, this is a danger that will only continue to increase here and across the globe. You don’t want to be the one who denies the reality until you suddenly become the victim.
Looking at Options
The major advantage with ‘off-site’ is that your backups are stored out of harm’s way from fire, flood, theft, or negligence. However, off-site backup storage cannot be used for online backups, It can be logistically tedious and there is a risk of damage in transit.
Cloud backup fans love cloud backup because it’s:
a safe distance from your location
Ideal for use with scheduled backups over a WAN or Internet connection
Incremental backups only transfer changed portions of files resulting in lower bandwidth usage
Very reliable with the use of redundant drives
You can access your data at any time
An ‘Undo’ button
Whatever the damage was, it needs to be undone. Continuous Data Protection provides the best Recovery Point and Time Objectives of any data protection solution.
Consider a virus causing damage, or a user deleting a critical file. A rollback volume is created for any point in time prior and served back to the application server, with no interruption to the production volume.
If necessary, a ‘bare-metal recovery’ means: “I’m going to take a machine that has no software on it, and bring it to the state that the initial server was in before it crashed.” The hardware must be identical in every detail for this to work cleanly.
If you backup regularly and store the data off-site, you’re most of the way to security. You can do this across a WAN from one disk to another.
A complete image of your disk drives and servers are mirrored. The image allows you to restore the system quicker than reinstalling an OS and copying files.
Some disasters have a very broad geographical footprint. So, 80 to 160 kilometers away is logical with your copy. Doing that on a WAN can be expensive if there is a lot of data to move.
Tiering – a Data Management Solution
The data gets first written to really fast storage, where it’s used during the time when it’s accessed frequently. At a second stage it is migrated to slower storage, with a greater capacity and lower costs. Finally it is migrated down to tape.
If this is done in a rigorous way, about 60% of your data will be down at the tape layer, and this dramatically reduces the costs of your infrastructure. The savings can be from tens of thousands to tens of millions.
