It might turn out that the computer you are trying to back up is overloaded with tasks in the given time frame, which might result in performance issues during the backup or even downtime for the whole computer. Slow performance of the backed-up computer.If there is no way you can enhance your upload speeds, then you should think about backup data prioritization and choose which mission-critical data to upload first. Here you should find an appropriate time and settings that will allow you to use the maximum-possible network throughput without affecting your company’s operations.

And, while you may be angry with the vendor of the backup solution, you are still responsible for returning the data to a working state. Your backups need attention and they can fail. You should then expect to have to fix issues from time to time, until your setup is flawless.Īnd 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.
