Hi
I can't get to the gui (removed a pice card - proxmox runs, but the the gui doesn't work)
gui might have to be fixed by a re-install, but first... backups!!

so from the command line:
Code:
vzdump 210 –dumpdir /backup –mode stop
400 Parameter verification failed.
vmid: invalid format - value does not look like a valid VM ID
any ideas? (yes - I made the backup dir)

It a common issue that network devices (whose name depends on the PCI ID) change their names when you add or remove PCI(e) devices because the PCI ID are assigned sequentially. Lots of threads about that on this forum: use ip a to find the new name and adjust /etc/network/intefaces accoridngly.

Not enough information yet. Maybe you just mixed up the order of the command-line parameters? You can schedule backups using the Proxmox GUI.
 
Backup can be done by the GUI, but not by command line - In my case, where storage is ZFS

Your command line is wrong and it tells you:
vzdump 210 –dumpdir /backup –mode stop 400 Parameter verification failed. vmid: invalid format - value does not look like a valid VM ID

The characters should be - instead. Maybe you copied it from a website that prettifies (and therefore changes) characters?

EDIT: It turns out, thanks @Neobin, that it's supposed to be two minus signs: --.

I used the minus sign, is this not correct?
 
Solved - as @leesteken said RTFM - read the manual!!!
I mis-read, there are two minus signs in the parameters for vzdump (not one as dummy here used!) - sorry for wasting peoples time!
vzdump 100 --dumpdir /mnt/pve/nfsStore
works just fine

it should also work with a single actual minus sign, just tested:
Code:
root@pve8a1 ~ # vzdump 100 -dumpdir foo     
INFO: starting new backup job: vzdump 100 --dumpdir foo
INFO: Starting Backup of VM 100 (qemu)
