Sudo sshd -T | grep "\(ciphers\|macs\|kexalgorithms\)"įor all-in-one installations, you can subtract 2 GB of memory resources from each but one role.
You can run the following command to verify the list of allowed algorithms:
Supported for backward compatibility: hmac-md5, hmac-md5-96, hmac-sha-256-96, hmac-sha1-96, hmac-sha2-512-96, hmac-ripemd160, , hmac-sha1Įnsure that your SSH configuration on the Linux server allows to use at least one cipher, KEX algorithm, and MAC algorithm from the table above. Recommended: diffie-hellman-group-exchange-sha256, diffie-hellman-group14-sha256, diffie-hellman-group15-sha512, diffie-hellman-group16-sha512, ecdh-sha2-nistp256, ecdh-sha2-nistp384, ecdh-sha2-nistp521, curve25519-sha256, for backward compatibility: diffie-hellman-group1-sha1, diffie-hellman-group14-sha1, diffie-hellman-group-exchange-sha1 Recommended: aes128-ctr, aes192-ctr, aes256-ctr,, for backward compatibility: 3des-cbc, 3des-ctr, aes128-cbc, aes192-cbc, aes256-cbc, arcfour, arcfour128, arcfour256, blowfish-cbc, blowfish-ctr, cast128-cbc, twofish-cbc, twofish128-cbc, twofish128-ctr, twofish192-cbc, twofish192-ctr, twofish256-cbc, twofish256-ctr To avoid negotiation problems between Veeam Backup & Replication and a Linux server, the latter should use ciphers, Key Exchange (KEX) algorithms, and MAC algorithms compatible with SSH libraries supported by Veeam Backup & Replication :
However, if you plan to restore Microsoft Exchange items from the Veeam Backup Enterprise Manager UI, you must install Veeam Backup Enterprise Manager on the domain member server from the Microsoft Active Directory forest in which Microsoft Exchange mailboxes are located. The machine on which you plan to install Veeam Backup & Replication does not necessarily need to be a domain member.
Mind that you cannot install Veeam Backup & Replication and Veeam Backup Enterprise Manager on a machine running Microsoft Windows Server Core. You can assign roles of a backup proxy, backup repository, WAN accelerator, Veeam Cloud Connect infrastructure components and tape infrastructure components to machines running Microsoft Windows Server Core. Backup infrastructure component roles can be co-installed. If possible, install Veeam Backup & Replication and its components on dedicated machines. We do not recommend to install Veeam Backup & Replication and its components on mission-critical machines in the production environment such as vCenter Server, Domain Controller, Microsoft Exchange Server, Small Business Server/ Windows Server Essentials and so on. Make sure that servers that you plan to use as backup infrastructure components meet the system requirements listed below.Ĭoexistence with Mission-Critical Production Servers
