RE: [cobalt-developers] CMU and Tar to transfer sites from one Raq3 to another

[ProServe - Peter Batenburg <peter@xxxxxxxxxxx>]

Hi,

How would you resolve the problem that every site gets new sitenumbers?
And how would you resolve the users having new index numbers? neigther
rsync or tar could help you with that. The only solid solution would be to
add some code to the CMU that makes a seperate index file containing all
files, and what users/sites (in www.FQDN format) owns it. Then when
restoring with the CMU it would have to take the index file, and use that
to change all the permissions. It would have to lookup the FQDN to the
site number. As an extra feature it could also create a logfile with
files that couldn't be restored. (Or somekind of double check)
The other solution could be to tweak the CMU so it will not
restore the files and change permissions to admin.siteX but
nobody.siteX.

With kind regards,

Peter Batenburg
