Move backup & save related stuff from Buffer to SharedBuffer

Browse Source 
Various methods of Buffer should be rather methods of SharedBuffer. This
commit doesn't move all of them to SharedBuffer yet, only those that
need to be moved to SharedBuffer in order to be able to request creating
or removing backups in other SharedBuffer methods.
