Moving 105GB mailbox to remote storage VPS, keeping it fully accessible/searchable — safe way to do this on HestiaCP?

I have a mail domain with about 105GB of mail data on my HestiaCP server, taking up a lot of local disk. It’s all legit data (large attachments), nothing to delete.

I have a separate 1TB storage VPS I could use to move this mail to.

Question: is there a safe way to move this mail off the local server onto that storage VPS, while the users can still access it normally in Roundcube/Outlook and still search and find old mail like nothing changed?

Has anyone done this on HestiaCP without breaking mail quotas, backups, or the panel itself? Looking for the safest/simplest approach, not trying to overengineer it.

Thanks!

Use the storage vps as network drive. Performance will depend on how far it is away and which protocol you use. If close by easiest is sshfs+autofs.

Set it up as mount outside the user scope first and rsync everything into it. Then at some point stop mailservers for a moment, rsync the diff and remount in place of the user mail dir.

nbdclient also works quite well and handle multiple parallel connections if latency is am issue.
