backup failed

I use this to backup nebula data, and it report error below

look like it doesn't support v2.6.0

Dear @steinliber,

Sorry, the master head nebula-br is designed for 3.0 + nebula graph only, which will be released in one-month :).

For 2.6.0, please try using the v.0.5.0, while it's not recommended(not released) as in nebula graph 3.0+ nebula-br comes with an agent-based design(to decouple SSH), if possible, it's recommended to use nebula 3.0+ nebula-br master.

Thanks!
