![]() ![]() At least one of the backup solutions must be fully automatic.If you still have an older version of that file or an older backup, that at least gives you a chance to recover the data. That makes those backup worthless as well. If a file accidentally gets corrupted (by bitrot, a software bug, or another accident), your backups will also contain a corrupted file. Ideally one of the backups also contains versioning data, meaning that it is not just the current version of files that gets backed up, but also older versions.That way you know the backup is not corrupted and you remain familiar with the proper procedure to restore files. From time to time you need to check your backups by restoring a few files from the backup.This ensures that if one application fails or stops working, the second backup mechanism still guarantees you have a full set of data. The two sets of backup data are ideally created using 2 different backup solutions or mechanisms.There are a few other recommendations for ensuring your data are safe: You can however also store hard drives with company data at home or keep a copy of data at your parent’s place. With these backup solutions, the data are stored in a datacenter, possibly in another state, country, or continent. Many prefer a cloud-based backup solution, like Carbonite, Crashplan, or Backblaze. This ensures that if a fire, theft or malware leads to the loss of the onsite data, there is still a spare copy at the other location. You must have 1 offsite set of backup data.If the drive dies, you lose both the original files and the backup! This means you should not store a backup of a disk on that same drive. The original files and one set of backup data can reside at the same location but they must be stored on 2 different media.That means that next to the original file, there must be two backup copies. You need to have 3 copies of your data.To make sure you never lose essential data, consider implementing a 3-2-1 back-up approach: ![]()
