Dump BU with 2G of space at server

Hello misc

I have one VM server at vultr, they have a tool to keep snapshots which
works correctly.

My point is because that server has only 2G of free space. What should be
the syntax for $ ssh my_laptop client dump -0 /my_/home/BU.dmp please.I
was not able to find the ssh-dump syntax, sorry.

Is it posible to do a full Bu dump -0 with this space? without the option -f

Thanks
