If you’re already working wholly or mainly in the cloud, then it makes complete sense to do your data backups to another cloud. Even if you’re still working in a traditional data center, it can make sense to back up to the cloud as your “offsite” copy, to facilitate quicker restores. With that in mind, here’s what you need to know about cloud data backup in Yuba City.
1. Even if you usually you a private cloud you may be able to backup to a public cloud
The basic process behind cloud data backups is as follows. Identify the data to be backed up, collect and compress and encrypt it. Transport it from one cloud to another and place it in storage.
There is more to it than that, for example, you will have to delete old backups as they become out of date and you’ll need to establish a process for restoring them, but that’s the basic principle. The important point is that the data is encrypted on your servers before it is moved off them and it stays encrypted right up to the point where it is either deleted or used for restoration. Ideally, you will keep control of your keys for maximum security.
For the sake of completeness, backing up to a public cloud does involve some technical challenges, although a good cloud data backup partner will be quite familiar with them. Once you have everything set up properly, however, using the public cloud for data backups can be a very cost-effective option.
If you’re still uncomfortable about entrusting your data to a public cloud, then you could, of course, set up a second private cloud. This would, however, have to be run entirely separately from your main cloud to be the equivalent of an off-site location.
2. If you’re in a public cloud, you should still backup your data to another cloud
Even if you’re completely confident in your public cloud provider, the fact remains that their data backups will only protect you against external threats such as cyberattacks and hardware failures. They will not protect you from erroneous deletions, be they accidental or malicious. This is usually the main reason why companies should back up to a second (usually public) cloud. The other reason is that it will also give you some protection against issues with your main public cloud provider.
3. A cloud data backup is a core part of a cloud disaster recovery plan
Backing up your data in itself does not qualify as a disaster-recovery plan (although it’s an integral part of one). You then need to think about how users would utilize that data. For example, what would you do about an operating system and applications? The answer to that question might be to switch to (another) public cloud or it might be to set up a second private cloud that would be activated only when necessary. Either way, however, you will need your data properly backed up and available for use.
4. You need a policy for controlling the amount of data you backup
You need to ensure that all relevant data is backed up for as long as necessary. It is, however, reasonable to stop and think about how to achieve this. In principle, you could make a full copy of your data each time you performed a backup. In practice, this approach is likely to be too lengthy and bandwidth-intensive to be a real-world option. The more common strategy is to take full backups interspersed with incremental backups (all data changed since the last backup) and differential backups (all data changed since the last full backup).
This controls the quantity of data you back up, but it does not necessarily solve the problem of “backup bloat”, in other words, data is continually backed up regardless of whether or not it is necessary. This can cost you money as cloud data backup vendors often used bandwidth and storage consumed as part of their billing criteria. You, therefore, need a strategy for making sure it is moved on periodically, be that into an archive or just deleted.
5. Responsibility for your data remains with you
Arguably this should go without saying, but it’s so important, that it’s worth highlighting on its own. You can delegate tasks to any IT services vendors who work for you, but you cannot delegate legal or regulatory accountability. This means that you need to be sure that you can rely on your IT services vendors to fulfill any obligations you hold.
For this reason, it’s generally safer to use cloud data backup vendors who are located in Yuba City (or at least near Yuba City), as opposed to cloud data backup vendors who offer services in Yuba City but are located elsewhere.
