ghettoVCB VS rclone

What are you trying to backup? VMs or the host itself? If host, hypervisors are usually meant to be disposable since you can import config from VMFS and VMX. You can backup configuration files within ESXi just to not redo complicated networking config. If you want to backup VMs, use any 3rd party software (yes, there are no built-in backups). If you are running free ESXi, you are pretty much forced to use agent-based backup or use scripts from Github - https://github.com/lamw/ghettoVCB.

All of the hypervisors you've mentioned (Proxmox, ESXi, XCP-NG) are capable of PCI passthrough, so it really boils down to which one you're comfortable with. ESXi is feature-limited regarding backups (unless you acquire a paid vSphere license or choose to use ghettoVCB).

ghettoVCB ( https://github.com/lamw/ghettoVCB ).

VMware ESXi Free (or vSphere Hypervisor) is a great option, however, it has limitations. The main limitation is that storage api is limited, and you can't use Veeam or alternatives to backup VMs. You can use ghettoVCB with free ESXi. https://github.com/lamw/ghettoVCB

Oh, got it. You can try using GhettoVCB with free ESXi. https://github.com/lamw/ghettoVCB

In case you are planning to use ESXi free, you can use ghettoVCB to backup your VMs. https://github.com/lamw/ghettoVCB

Back up the existing server's configuration and restore on to a new disk. https://kb.vmware.com/s/article/2042141 https://github.com/lamw/ghettoVCB

Veeam has no such option. For ESXi configuration backup you can use ESXi Configuration Backup Tool or GhettoVCB. https://www.vladan.fr/free-esxi-configuration-backup-tool/ https://github.com/lamw/ghettoVCB

Backups - either use Veeam at the OS level or leverage ghettoVCB to do backups from the ESX host itself using snapshots (I use the latter, personally) and replicate them to your backup NAS.

rclone: a command-line program to manage files on cloud storage.

Synchronise buckets with Sclone or Rclone

Says that Apple doesn't provide a multi platform API. It doesn't provide any official supported way to access iCloud from Windows, Linux.

There's a ticket covering everything you might ever want to know:

https://github.com/rclone/rclone/issues/1778

seconding rsync and syncthing.

the server could expose an smb or nfs share, the client could mount it, and then sync to that mount.

rsync over ssh also works, if you do not want to run smb/nfs.

this is also a cool tool https://rclone.org/

rclone [1] to dropbox. works since years without problems

rclone provides a special pCloud config option, which makes the setup straight forward. rclone can encrypt the data it uploads with its own encryption but not with the pCloud encryption. Therefore it can only upload data to the unencrypted pCloud folders, not to the Crypto Folder.

The arkclone project impliments rclone in ArkOS to achieve cloud saves. Not yet built in to ArkOS yet, and not a lot of recent traction on the pull request to get it added, but it can be installed manually.
