Backup vs. Back Up, Failover vs. Fail Over, Failback vs. Fail Back Tips

  1. The same applies to all words that can work as both nouns and verbs. For example, roll back and rollback, log in and login.
  2. You may encounter a situation where you need to describe an item that has been backed up. In this case, use the adjective backed-up spelled as a hyphenated compound word.

Examples

  1. Veeam Backup & Replication does not necessarily use a backup created by one job and one backup repository as a source of data. It can copy data from backups created by different jobs and even from different backup repositories.
  2. If you do not want to back up or replicate some files and folders on the VM guest OS, you can exclude them from the backup or replica.
  3. Failover is a process of switching from the original VM on the source host to its VM replica on the target host.
  4. If a VM becomes unavailable in case of a disaster, you can fail over to the VM replica and quickly restore services in the production environment.
  5. If you want to resume operation of a production VM, you can fail back to it from a VM replica. When you perform failback, you get back from the VM replica to the original VM, shift your I/O and processes from the target host to the production host and return to the normal operation mode.
  6. If you fail back from a VM replica to the VM in the original location, you can instruct Veeam Backup & Replication to perform quick rollback.
  7. You can power off running VM replicas on target hosts and roll back to the initial state of these replicas.
  8. To upload backed-up data to Amazon EC2, Veeam Backup & Replication uses an auxiliary EC2 instance — a proxy appliance.
  9. For every disk of a backed-up machine, Veeam Backup & Replication creates an empty EBS volume in Amazon EC2.
