Contrary to what some IT professionals believe, backups are not âset it and forget itâ. You need to plan their execution carefully, build and set up a solution. You should then expect to have to fix issues from time to time, until your setup is flawless.
And even once your backup setup is flawless, major parts of your infrastructure may change (such as, for example, you decide to switch from on-premises solutions to cloud applications and cloud-native data); and so you start all over again.
Your backups need attention and they can fail. And, while you may be angry with the backup solution, you are still responsible for returning the data to a working state. In this blog, we define the typical areas for backup failures and provide guidance on how you should deal with them.
Damaged backups may not be the most frequent cause of losing backup data, but it’s for sure one of the most frightening. Just imagine a situation where your solution reports that backups have successfully been uploaded to the storage and then, one day, when you need to recover them, your data is corrupt.
Why is this a terrifying scenario? Because, without proper recovery tests, you are never sure that your data is recoverable. As an IT pro managing backups, you should either check your data consistency frequently and perform recovery tests, or you should be aware that your data could be corrupt.
But what are the typical reasons for data to be damaged? Here are the most common cases:
So how do you protect yourself against damaged backup? First of all, you need to employ a modern-day backup solution with a proven, stable history. Some backup solutions even include automated data consistency checking in their offering.
Secondly, you should test the recoverability of your backups from time to time, to be 100% sure you can get your data back.
Sometimes, although people might think that their backups are fine, they are not merely damaged, but do not exist at all. This typically happens when a system administrator relies on his/her memory in order to start the backup, rather than on setting up a schedule.
The second reason for missing backups could be that the administrators forget to, or do not know how to, set up alerts about any issues with backups.
So, to avoid losing your backups completely, you should:
A less dramatic technical issue with backups is that they might take ages to actually finish, thus slowing down your progress and messing with your recovery time and recovery point objectives.
The main reasons for slow backups are:
Lastly, and quite surprisingly, you could lose access to your backup storage or backup media, thus losing precious time during a disaster. There are several main reasons for losing access:
Diversify the Risks
To avoid all that, you need to create a comprehensive plan of how you test your backups. Create a great testing environment and make sure that you have covered everything that is vital to your business, thus ensuring you a good night’s sleep.
With Google cloud storage, you can have your backups automatically moved from higher priced to lower priced tiers to save on money(Standard, Nearline, Coldline and Archive tiers), and it’s perfect for long-term retention. When using Google Cloud storage to back up business data, you ensure the data can easily be accessed from anywhere, backups are kept safe, and costs are cut.
