Two Servers with One client

[GnU]

Hello,

I use an ubuntu server on which urbackupserver runs natively.
The clients are also Linux clients.

I found this on the subject:

Two UrBackup Server in the Same Net

Yes, but either the servers need to use the same set of keys, or you need to manually add the keys to the agents. Agent automatically add the keys from the first server they see.

but I am a bit confused

/usr/local/var/urbackup $ ll
total 5020
drwxr-xr-x 4 root root    4096 Apr 25 14:15 ./
drwxr-xr-x 3 root root      22 Apr 25 12:58 ../
-rwx------ 1 root root     156 Apr 25 12:59 access_keys.properties*
-rwx------ 1 root root   81920 Apr 25 12:58 backup_client.db*
-rwx------ 1 root root   32768 Apr 25 14:18 backup_client.db-shm*
-rwx------ 1 root root 4956392 Apr 25 14:18 backup_client.db-wal*
drwx------ 2 root root     117 Apr 25 14:17 data/
-rwx------ 1 root root       0 Apr 25 14:15 new_server_idents.txt*
-rwx------ 1 root root      30 Apr 25 12:58 pw_change.txt*
-rw-r--r-- 1 root root      30 Apr 25 12:58 pw.txt
-rwx------ 1 root root     919 Apr 25 14:15 server_idents.txt*
-rwx------ 1 root root     217 Apr 25 14:15 session_idents.txt*
drwxr-xr-x 2 root root    4096 Apr 25 12:59 tokens/
-rw-r--r-- 1 root root   31281 Apr 25 12:58 updates_h.dat
-rw-r--r-- 1 root root       3 Apr 25 12:58 version.txt

So here there is the server_idents.txt and new_server_idents.txt. Which file should contain the second fingerprint of the second server? The server_idents.txt contains the fingerprint of the first server.

I have tested both and restarted the client but had no success.

Background:
Currently there is a native urbackupserver installation on a system that needs to be replaced. Therefore, there is now another server and I would like to move the systems one by one.

How i can use two servers on one client ?

My experience with UrBackup isvery limited but i believe the administration manual briefly touches your scenario. Take a look at Section 4.3 Client security.

In there they talk about server credentials, server identities and private/public keys but, on the last paragraph it says

“If you want to have several servers to be able to do backups of a client you have two options. Either you manually supply the server credentials to the client (by copying them into ’server_idents.txt’) or you give all servers the same credentials by copying the same ’server_ident.key’, ’server_ident_ecdsa409k1.p riv’ and ’server_ident_ecdsa409k1.pub’ to all servers”.

Take a look at that entire section of the manual and maybe you can figure how to do this.

Hello,
Read this.

Two UrBackup Server in the Same Net

lars_b: Find your next server in IP address order. Go to that server’s status page and click Add New Client. Highlight and copy the Server Identity code to the clip board or paper (no spaces). Cancel out of there. After you have installed a client and it has successfully automatically connected to the first server it finds in IP address order. Open the UrBackup program folder on that client. It could be “C:\Program Files\UrBackup” Copy server_idents.txt to the desktop. Open the copy and…
