UCSM 4.2 (3j) backup failure on the remote host

[yogananda-shivakumaraiah]

We have UCSM 4.2(3j), and backups are failing to a remote Linux box.

We have the following error codes in the UCSM

[Wes Austin]

Can you share some more details about your configuraiton of the backups? Filename? protocol? etc

Do regular local backups succeed? Has this ever worked before?

Its hard to provide guidance based on just the error message

[yogananda-shivakumaraiah]

Local backups work fine, and both local and remote backups have been successful in the past.

We are using SFTP as the protocol and the filename is below in the screenshot

Thank you

Internal database backup gets succeed and internal system backup fails when we trigger a full state system backup.

This is likely a SSH version/algorithm/key/kek issue.
Either UCSM is rejecting a old Linux SSH version, or UCSM doesn't like very new Linux SSH version. (or vice versa.)
What exact Linux distro are you using?

[yogananda-shivakumaraiah]

We are on SUSE Linux on the SFTP server

[yogananda-shivakumaraiah]

We have SUSE Linux as the backup server.  Could you please let me know how we can validate the SSH Cipher Suites UCSM is using?

Hi @yogananda-shivakumaraiah ,

The error suggests UCSM is unable to locate the specified path on the remote SFTP server:

ERR-DHLD-no file: /commands-sftp:/opt/backup/backup-upload

To resolve this:

– Ensure the directory /opt/backup exists on the remote Linux server.
– Confirm the SFTP user has correct write permissions.
– In UCSM, use the path as /opt/backup without the commands-sftp: prefix.
– Double-check the remote hostname, username, and port configuration.

Also, verify firewall rules and SELinux/AppArmor settings if applicable.

Hope this helps clarify the cause and resolution!

1 Can you ssh from UCSM to the backup server? This will confirm that firewall ports, user etc are working. 

UCS-B# connect local
R1UCSM02-B(local-mgmt)# ssh $USER@$SERVER

UCS-B# connect local
R1UCSM02-B(local-mgmt)# ssh $user@$server

2 Can you configure the file path to an absolute file path (I see the previous user suggested the same, my suspicion is this is the root cause)

/home/$USER/ucs_backups

Getting this permission error while I'm trying to SSH to the SFTP server using the backup username we have configured.
