Can I Use an Incremental Backup to Restore Data After a Full Backup Is Deleted?

Yes.

CBR allows you to use any backup, no matter it is a full or incremental one, to restore the full data of a resource. By virtue of this, manual or automatic deletion of a backup will not affect the restoration function.

Suppose server X has backups A, B, and C (in time sequence) and every backup involves data changes. If backup B is deleted, you can still use backup A or C to restore data.
