Linux backup to NFS cmd help

I am trying to backup to a NAS, currently this machine does not have Samba, and I would prefer not to install it. When I run the command below I get this:

trueimagecmd --filename:nfs://nas2.sgc3.com/Data:/ast.tib --harddisk:disk1 --create --progressn --compression:2

Command line parameters are incorrect or incomplete.

Also, I mounted the NFS share to misc/local, and then ran..
trueimagecmd --filename:/misc/local/ast.tib --harddisk:disk1 --create --progressn --compression:2

and still got "Command line parameters are incorrect or incomplete."

 

Hello sbn,

Thank you for choosing Acronis Disk Backup Software.

Please accept our apologies for the delay with the response.

Please note that the command should be typed as follows:

trueimagecmd --filename:nfs://nas2.sgc3.com/Data:/ast.tib --harddisk:1 --create --progressn --compression:2

Namely, do not type disk.

An image may contain data of more than one hard disk. In that case, separate disk numbers by commas, e.g.: --harddisk:1,3

Thank you.
