Every night, Devisto takes an automatic backup of every project. Every backup is kept for 30 days. A backup contains a complete copy of the project (database and assets).
You can view the existing backups of a project by going to Settings → Backups.
At any give time, you can take a manual backup of a project. Click Create Backup in the upper right corner to create a manual backup. Optionally, you can give the backup a message to recognize it later, for example 'Backup just before big product update'.
Taking a backup can take several minutes, depending on the size of your project. We try to make incremental backups whenever possible. So if there were not a lot of changes since the last backup, the process should be pretty fast.
To restore a backup, right-click on the backup and choose Restore Backup.
An existing project will never be overwritten by a backup. Instead, when you restore a backup, a new project will be created from the backup. So you have to choose a new name and slug for the restored website.
