Incremental or Differential Backups

Hello Mike!

Welcome to our Forum, we're glad to greet you here! I understand your concern and will be glad to shed the light onto the situation.

An incremental backup contains all changes that have been made since the latest incremental or full backup was created. If one full backup and several incremental were created, all of these backups must be saved in the same folder so that you will be able to restore the data. If one of incremental backups or a full backup is deleted, there is no way to restore the set, since all backups are dependent on each other.

A differential backup contains all changes that have been made after the full backup creation. To restore a differential backup, Acronis True Image must match the differential backup with the original one.

So, If your objective is to reduce backup size and backup time, then the best strategy would be to create incremental backups. On the other hand, if you want to increase backup reliability, by not having to rely on a chain of incremental backups, then differential backups would be the best solution.

Anyway it's up to you to decide. I'd also advise you to check this article regading incremental and differential backups for more details.

Should you need anything else or have any further questions - feel free to contact us at your earliest convenience, we will be happy to help you!

Thank you!
