It appears my /opt/ folder isn’t persisting between boots. Any bright ideas how I resolve this? Or can I “install” vertical backup directly to one of my datastores?
Which ESXi version is this?
Yes, you can install vertical to any directory, including those under a datastore.
Latest ESXi 6.5.0 update 1.
Perhaps worth updating the documentation/install guide?
I installed on one of my datastores, rebooted and it has persisted, bingo!
Is there any more detail around the saving of passwords? The guide brushes on key value pairs in a json file, but I could use some more detail, a sample file perhaps?
This is a sample .verticalbackup/passwords file that provides the SFTP password:
{
"ssh_pass": "12345678"
}
