When you need to back up your servers, you have a lot of things that could potentially go wrong standing right in front of you. In most instances these are things that seem like "no duh" issues after the fact, but it is easy to get caught up in the hustle and bustle of running your business and forget all about them at the time. For most business owners, just having a backup solution in place is something of an accomplishment. But you can't rest on your laurels and hope that having "something" is going to be enough. You need the best, and you may not currently be getting it with the solution you have in place at this moment.
Any kind of server backup solution is going to require a lot of variables to line up properly. If any of these variables do not line up as they should, you are going to find yourself in trouble. You need to make sure that as many variables work in your favor as possible and get anything that might be standing in your way out of it as quickly as you can.
Any kind of server backup service is going to need you to keep your servers in good condition. While you can often outsource all of your servers, you need to make sure that your data has a good starting point in order to be sure that it is backed up properly. As the old saying in the hacker community goes, garbage in equals garbage out. If your servers are suffered from some deferred maintenance, the best time to get them squared away is as soon as humanly possible. Getting things in shape on the home front is a great way to make everything work more efficiently.
Naturally, the server backup services you choose to use need to keep everything as automated on the backup front as possible. Backing up files should not involve having to repeatedly physically perform any kind of action that could easily be done incorrectly or forgotten about. Human beings are fallible creatures and everyone makes mistakes from time to time. Systems, on the other hand, are generally capable of going through numerous repetitions without any kind of failure. If something fails, fixing the system is usually a fairly simple and one time task that a suitably skilled person can do relatively easily. If you have been working with an individual or a group that does not use automation in the backing up process, you know that can cause a host of different kinds of problems that can range from simple forgetfulness and errors all the way to sabotage.
Another problem that far too many server backup systems have is actually too much in the way of systematization. Even when your systems work extremely well, they still need to be both managed and humanized to some extent. The only way to do this is through having good, human controlled customer service in place. If your backups have been failing in any way, you may be able to trace the problem back to an error in communication between your company and the backup company. When someone doesn't say something or a question goes unanswered, problems tend to begin to happen within the process immediately.
Of course, another solution to your problem could always boil down to the frequency at which your files are being backed up. If your file backups are happening too often if could actually be slowing down your servers and hampering your company's efficiency overall. By contrast, if your server backups are not happening often enough than you could be sacrificing key data that would get lost the first time something bad happened in your office.
On the whole, there are a lot of things that can always go wrong when you have a backup system in place. When your systems are working well, you do not generally have to think about them. But when something goes wrong you often know about it immediately -- although the knowledge still generally comes too late to be useful in anything but learning lessons from failures. In any case, there are some mistakes that you do not need to make in your server backups.
