Backup Task

Select the content to back up. Note: Both types can be scheduled.

1. Full Backup
   Full Backup will back up all the database data every time the task is scheduled to work.

2. Incremental Backup
   Incremental Backup will only back up the delta (changes made) of the data since the last backup that has occurred.

Schedule the Backup Task time using a Cron Expression.
(eg. "0 0 12 * * ?" means "0 seconds, 0 minutes, 12pm (noon), every day, every month")

Notes:

1. If only Incremental Backup is set, then a Full Backup will occur only in the first time that the Task is triggered,
   followed by Incremental Backups according to the scheduled time.
   The Full Backup that is done the first time will be either a 'Backup' or a 'Snapshot', depending on the type selected.

2. Data that is backed up in Incremental Backup is always of type 'Backup' - even if the Backup Task Type is 'Snapshot'.
   A Snapshot can only occur when scheduling 'Full'.

• A Full Backup is scheduled every day at 02:00 AM - and in addition to that -
• An Incremental Backup is scheduled every 6 hours
  

Select backup destinations and enter your credentials for each

Note: More than one can be selected

Available destinations:

• Local - Set a folder of your choice (any directory that can be accessed from your machine)
• Amazon S3
• Microsoft Azure
• Amazon Glacier
• FTP - Set your FTP protocol & server address

When the cluster is down (and there is no leader):

• Creating a new Ongoing Task is a Cluster-Wide operation,
  thus, a new Ongoing Backup Task cannot be scheduled.

• If a Backup Task was already defined and active when the cluster went down,
  then the Backup Task will still continue to execute on its defined schedule (on its responsible node).
  But, it will fail to be reported to the cluster and may be run again after the cluster has recovered.

When the responsible node is down

• If the responsible node for the Backup Task is down during the scheduled time,
  then another node from the Database Group will take ownership of the task so that there are no gaps in your backups.
  

RavenDB's External Replication provides you with an off-site live replica/copy of the data ('live' meaning that any changes in the database will be reflected in the replica once they occur).
If one database is down, the replica can continue its work, thus greatly improving availability.
This is also quite useful if you need to:

• Shift operations to a secondary data center
• Share the workload across more than one server.

But a replica isn't a backup... It doesn't present good solutions for many backup scenarios. For example, backups can:

• Protect you from an accidental collection delete
• Tell you the state of the system at, say, 9:03 AM last Friday
• Protect you from various cyber attacks

A backup keeps an exact state of the database at a specific point in time and can be restored.

• A new database can be created from a Backup
• This can be done with both 'Backup' & 'Snapshot' types
