The full backup copies all the selected data. The incremental copy only the changes since the last backup of the string.
In brief….Many softwares create complete synthetic backups or automatically managed incremental chains. The restoration test counts more than the name of the mode.
Solution A….
Full backup
The complete backup is an autonomous point containing the entire protected perimeter.
Key points…
- Simpler restoration
- More important time and space
- Base of many backup strategies
Solution B….
Incremental backup
The incremental backup reduces the amount copied to each execution by transferring only new and modified versions.
Key points…
- Faster daily execution
- Savings in space and bandwidth
- Chain and software dependent restoration
Comparative table….
| Criterion…. | Full backup | Incremental backup |
|---|---|---|
| Volume copied | All perimeter | Only changes |
| Backup time | Longer | Shorter |
| Restoration | Simple from the full point | Software restores the chain |
| Risk | Window and storage | Dependence on the chain integrity |
Choose Full Backup if…
You can support the necessary window and volume, or you periodically create a new reliable base.
Choose Incremental Backup if…
You have frequent backups, large volume and reliable repository with regular verification.
Key takeaways
Many softwares create complete synthetic backups or automatically managed incremental chains. The restoration test counts more than the name of the mode.
