This should be done very carefully and by more than one person to get different perspectives on what should be backed up.
After the mapping of business systems is the time to categorize. how critical is the recovery time!?

Today, companies have big challenges to deal with complex storage infrastructures and to meet the requirements of the data security. For increased availability requirements and storage for it really to be selective in its approach to enterprise backup. Among the smaller companies it is very common with so-called file-level backup, which means that the backup server only retrieves files from the server / computer from certain directories. It can mean much longer up-time after a crash when the operating system and applications must be reinstalled before the restoration of data can begin. There are of course quite a long time and not to forget, the backup must be restored. It takes different lengths of time depending on the amount to be restored. Large amounts of data = long time.
A much better solution to backup as many medium and large companies working with today’s incremental backup. The difference is huge. As previously mentioned, the focus should be more recovery time than the backup. With incremental backup to backup an entire environment that is The operating system, your applications and files. This form of backup results in a much shorter recovery time. In a crash the server / computer you only need to run the restore to get everything back exactly as it was before the crash.
So whether you are a sole trader or a listed company with business-critical data, incremental backup is a good investment.
