Keep your backup safe from ransomware

The most effective way to protect your files from Ransomware is to have a backup and for achieving that, an excellent backup plan is a must.

As we know until now all Ransomwares infect systems by encrypting every important files such as : documents and backups also delete volume shadow copies, so if you have your media in which backup is written attached to your files system either via network or through other ways the chance that the backup files survive is near zero percent. So having only online backups is totally risky.

On the other hand every company needs an online daily backup to ensure, for example, it can recover accidentally deleted files in a daily basis.

The first solution that comes in mind is: “we can have offline backup” so let’s analyze ways to take an offline backup!

For having and offline backup you need to either attach/detach your backup media physically or write backup to a non-writable media. The former solution is not going to work in real life, because you can’t allow random staff to access the backup media and attach or detach it, and even if you can specify that person to do that it will not be sufficient and it will contain human error.

The second solution is not cost effective for mid-range businesses.

Having an in expensive backup system which takes daily backups on two separated medias on a schedule and automatically attach and detach them is a critical need for mid-range companies so they can have online backup for daily needs (recover accidentally deleted files) and also an offline backup to recover from ransom infection. In case of ransom infection the only data which is written between two set of backups are lost because the media in which backup is Witten in the time of infection may be encrypted by ransom.
