Oak Backup vs Déjà Dup
Déjà Dup is a simple - yet powerful - backup tool for Linux. Unfortunately it has two major drawbacks.
1. Déjà Dup stores backups in a custom format
When it comes to backing up your files, the simpler the solution the better it is. Unfortunately, Déjà Dup's backup format is not simple. It stores your backups in a custom format and is prone to data corruption as shown in these pages:
- Is there a way to repair corrupt deja-dup backups?
- How to recover from a corrupt Deja Dup backup, and set up an alternative
- Allow people to exclude corrupted incremental backup from chain
- Your backup appears to be corrupted. You should delete the backup and try again.
- DejaDup "Restore Failed, no backups to restore"
The last thing you want to know when you need to restore your backups is that they are corrupted and so they cannot be used to recover your data.
Fortunately, that's very unlikely to happen with Oak Backup because it stores your backups in plain files and checks the integrity of each file when it's uploaded to your cloud provider.
Moreoever, since Oak Backup stores your backups in plain files, you don't depend on any custom tools to restore your backups. You can simply restore your backups anytime with the UI or tools provided by your cloud provider.
2. Déjà Dup doesn't support Amazon S3
As of version 42, it's no longer possible to back up to Amazon S3 with Déjà Dup. Déjà Dup's developers decided to focus on more consumer-targeted cloud services such as Google Drive, instead of more technical cloud storage services such as Amazon S3.
