QA

install the core testing version with a cluster of two nodes, to test the work you can use a local backup on another node (you can suspend the vm to simulate a failure)

the testing version is ghcr.io/nethserver/core:3.2.3-dev.2

configure a backup of an application

• case 1 : backup is going well the first backup
  once the backup is done and finished you can go to the list of application and verify that we have the last stats of the backup, the duration of the backup, the time when the backup has finished and a green flag to advertise that everything is good

• case2 : backup is going bad the second backup
  suspend the destination machine, and trigger to start the backup, you will have a timeout about 2 minutes before to go to error. verify the status of the backup we will have a red flag, the duration, the end of task but no statistics

• case 3: backup is going bad the first time
  configure a backup of a module and suspend the destination machine before to trigger the backup. You will have a timeout about 2 minutes before to go to error. verify the status of the backup we will have a red flag, the duration, the end of task but no statistics
