I have no problem with backing up catalog on other server with less 
expensive storage space. But I do not see any use of old catalog backups 
at all. I would do "bscan into new catalog" in all cases except the one, 
where I have catalog backup newer than last data backed up and I need to 
recover it. I.e. database server crash or something like that. In all 
other cases I would not risk the possible complications...
