Simple tutorial - how to backup and restore OS in case something bad happens, so that you can sleep well.
With this solution, there is no downtime (when backing up). It is not a byte-to-byte backup, yet it can be used as one (with a few steps) as well.
There are multiple diff-based utilities out there.
I can recommend Duplicati which offers:
- Nice GUI
- Cloud support
- Encryption (AES/GPG)
If you don’t want to pay your hosting provider additional costs for sector-by-sector backups - you can give Duplicati a shot & upload your encrypted backup to one of many Storage Providers.
You can use the following folder filter to backup root except these virtual file systems:
Duplicati works well even on VPS. With numerous cloud providers support - it is enough to find one which offers at least the same disk size and you are good to go.
