No, these directories are not mounted on NFS. The scheme such: there is
a server (guardian) which does a backup, and there is a client (tux) on
which there are directories/test and/var/www/localhost/svn for which it
is done a backup. With a directory/test all is normal, I can restore
files from it, and here at attempt restore files
with /var/www/localhost/svn amanda deduces the following message:
(On tux I execute a following command:
amrecover daily -s guardian -t guardian -d file:/amandatapes/daily/)

amrecover> setdisk /var/www/localhost/svn
200 Disk set to /var/www/localhost/svn.
No index records for disk for specified date
If date correct, notify system administrator
