Install the latest update for Veeam Backup and Replication. This enables aes128-ctr, aes192-ctr, aes256-ctr, aes192-cbc and aes256-cbc in addition to the already existing 3des-cbc, blowfish-cbc, and aes128-cbc.
A more secure Ciphers line would be:
| Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes192-cbc,aes256-cbc |
6.x and 7.x:
Make sure that at least one of the following algorithms are included on your Ciphers line:
| Ciphers 3des-cbc,blowfish-cbc,aes128-cbc |
