How to integrate PBS server with CentOS client

[powersupport]

Hi,

We have a server with PBS Backup Server 1.1-1, and a centos server with a backup client installed

./proxmox-backup/target/release/proxmox-backup-client version
client version: 1.0.11

Can anyone advise how we can integrate these two servers? we need to back up the client VM to PBS server, a bare-metal backup

We couldn't find any documentation online regarding this


Thank you.

hi,

is centos server running on PVE, or is it standalone?

* if PVE
then you can just add your Proxmox Backup Server as a storage to your cluster, and selecting the backup server as target should be enough.

* if standalone
then you can configure your client to point to your backup server [0]

Hi
It is a standalone server


proxmox-backup-client backup root.pxar: / --repository root@pam@pbsserverIP: test --backup-id 'test1'

While running the above command we are getting the error as below


Error: parameter verification errors

parameter 'repository': value does not match the regex pattern
parameter 'backupspec': value does not match the regex pattern
parameter 'backupspec': value does not match the regex pattern
parameter 'backupspec': value does not match the regex pattern

Also, is it support bare-metal backup? I could only directories are able to backup using the command

Thank you

proxmox-backup-client backup root.pxar: /  --repository root@pam@pbsserverIP: test --backup-id 'test1'

your command has extra spaces which breaks the regex.

can you try like this:

proxmox-backup-client backup root.pxar:/  --repository root@pam@pbsserverIP:test --backup-id 'test1'

(remove the space after root.pxar: and pbsserverIP:

Hi,

The backup seems running now, let us monitor, also, we can only backup mount points using this method, is there any way to do a bare-metal backup for the servers? and any way to manage Backup/restore from the PBS interface, we couldn't see any options from the interface

Please advise and thank you for the help

what do you mean exactly?

if your VM is running on PVE, then all you need to do is to add the PBS as a storage. when you are choosing backup destination for your VM (from the PVE GUI), choose your PBS instance.

for restoring VM you can do the same, by selecting the backup server as storage in PVE GUI on top right of the VM backup tab and choosing the archive to restore from.

otherwise with the backup client you can do: proxmox-backup-client restore <snapshot> <archive-name> <target>, for example

$ proxmox-backup-client snapshot list --repository root@pam@pbsserverIP:test

Hi,

Is there any way to do a bare-metal backup for the servers, That is to restore the backup content to a remote server

Please advise and thank you for the help

Hi,

We have already initiated the backups yesterday and seems like it is not working. As I can see the task scheduled for the backup still running. Please see the screenshot pbs-ss1.png.



Also, when opening the backup content showing an error message as shown in the screenshot pbs-ss1.png


We ran the below command in order to initiate the backup,

===========
proxmox-backup-client backup root.pxar:/ --include-dev /boot --repository root@pam@<IP-Address>:test --backup-id 'test1'
===========

Could you please advise how to troubleshoot this issue?

Thank you.
