After each job run, NAKIVO Backup & Replication creates a recovery point for each VM in the Backup Repository. A recovery point represents the backed up VM as of a particular moment in time and allows you to recover individual files, application objects, or the entire VM from the Backup Repository. You can specify how many recovery points you want to be retained in the Backup Repository using the Grandfather-Father-Son (GFS) backup rotation scheme.
When the Amazon S3 Backup Repository is selected as the only backup destination, you can apply S3 Object Lock to recovery points in this repository. With S3 Object Lock applied, the recovery points are immutable and stored using the write-once-read-many (WORM) model. Immutable recovery points cannot be overwritten, deleted, or changed until a specified period has expired.
Here you can set the retention settings for the backup job. Set the following options:
- Keep x last recovery points: Retains the specified number of last recovery points for each VM in the job.
- Keep one recovery point per day for x days: Retains one last recovery point per day for the specified number of days.
- Keep one recovery point per week for x weeks: Retains the last available backup of every week for the specified number of weeks.
- Keep one recovery point per month for x months: Retains the last available backup of every month for the specified number of months.
- Keep one recovery point per year for x years: Retains the last available backup of every year for the specified number of years.
In this section, you can configure the Make recovery points immutable for x days option. The recovery points remain immutable for the specified number of days.
For the Immutability section to be available, the following conditions must be met:
- Only Amazon S3 Backup Repositories must be selected at the Destination page of the wizard.
- Object Lock must be enabled for the Amazon S3 bucket where your Backup Repository is located.
