STSADM only offers backing up a Site Collection to a single file, so that's
what we do. The resulting file is roughly the size of the Site Collection,
as reported in the WSS interface.
The problem I referred to was encountered when I tried to restore all 1100+
sites. Basically I wrote a for loop that walked through the directory where
the backup files where and it ran STSADM -o restore to restore them. Of the
1100+ files, 10 refused to restore. Like Patrick said, besides that we've
had pretty good luck.
I will tell you that the STSADM method doesn't scale very well. Using one
IIS server we are able to back up around 12 GB of content per hour. If your
installation is going to get very large, it's going to take a while to back
it up using this method.
