## Symptoms

- * When the user tries to create a backup to an SCP server, the backup fails with the following error if there is no connectivity to the SCP server:  

  `TESTFW> add backup-scheduled name "DAILY" scp ip 1.2.3.4 path /user/checkpoint/ username <<USER>> password <<PASS>>`  
  `bad parameter.`  
  `NMBCK0083 Timeout waiting for response from database server.`

  <br />

* In a parallel session, a tcpdump shows outgoing TCP packets to the SCP server on port 22:  

  `tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes 11:39:21.182974 IP (tos 0x0, ttl 64, id 61985, offset 0, flags [DF], proto TCP (6), length 60) 1.2.3.100.34116 > 1.2.3.4.22: Flags [S], cksum 0xd756 (correct), seq 110389312, win 29200, options [mss 1460,sackOK,TS val 2792033 ecr 0,nop,wscale 10], length 0`

  <br />

## Cause

In R80.40, the SSH host key is grabbed during the setup of the scheduled backup.  

If this fails (for example, because there is no connectivity to the SCP server), the backup job will fail, as well.  

This is done for security reasons, to prevent MITM attacks from capturing the backups.
