[GIS.lab] switching between backups

[Ludmila Furtkevicova]

Hi,

just to be sure ...

I think it is possible and useful to have symlinks to images in backup
directory and just switching between them according to needs.
I am conscious that clients boot from current image. My question is:

Is it necessary to always extract corresponding root from backup? Is'nt
change of image (new symlink) enough?

See my attached schema.
Thanks.

L.
