With disasters come the risk of losing data that’s critical to your business. It should come as no surprise then that some companies that have lost critical data end up going out of business within a year. Not having a disaster recovery plan in place risks affecting not only the business operations but also the clients who make use of the companies’ products and services.

A solid backup plan is then a must. And when planning for disaster recovery, here are the different backup solutions you can consider to protect your data and gear you up for disaster recovery.

Full Backups

This solution allows you to select the folders and files from your drive to backup. Each time this runs, it copies all the selected files and folders in their entirety to your backup storage. It is important to note that this requires a lot of time and may need more storage space than usual.

Differential Backups

Differential backups are usually done partnered with full backups. What it does is it copies only the files and folders that have changed since the last time they were fully backed up. This type of solution overwrites the changed files multiple times. This takes up less time and space but data recovery through this can get complicated as you’d need to do a two-step recovery – backup from most recent full backup and then apply the last differential backup.

Incremental Backup

This is very similar to differential backups that it’s also in conjunction with full backups. The only difference is that it copies the files and folders that have since changed from the last backup, no matter the type of backup. This means it doesn’t copy the files that have been changed multiple times, which results in a quicker backup time and smaller storage space needed than differential backups. However, backing up from incremental backup becomes tedious as steps can take as many as how you set up incremental backups. You recover your data by applying the most recent full backup and apply each incremental backup.

System Image Backups

This is a higher level backup solution that backups your files by creating a system image of the drive, copying section by section instead of file by file. It doesn’t just include files and folders (like full, differential, and incremental backups), but your entire drive – operating system, programs, drivers, system settings.

IT and support Technicians usually prefer this as this could certainly guarantee full restoration of a computer that’s crashed to the state it was when the system image backup was created. This means they won’t have to create your entire system from scratch and put the files and folders where they belong. Downside to this is takes quite a long time to backup and requires large storage space – as large as your drive. This method also can’t restore just one file (even if that’s all you needed), you’d have to re-image the drive and restore all files.

Continuous Data Backups or Versioning

This backup solution backs up data that has changed every time you save. However, they do not overwrite the data, but takes a snapshot of the modified data, and keeps each snapshot taken. This then allows you to restore a file to a version at any particular point in time. You can also pre-set the intervals to create near-continuous data backups and you can restore a file to any version at a particular interval.

Loss of data is minimal in this case but it does take up a lot of bandwidth and resources. This could also prove to be more expensive as it uses continuous data protection (CDP) technology.
