I was wondering how amanda estimates the backup size ?
is there a switch to tar to estimate the archive size without
generating the file ?
For the estimate phase Amanda uses the "--file /dev/null" option
of gnutar, and gnutar has a special optimisation that if it detects
output to /dev/null, it will actually not read any bytes of files, but
just make statistics.
For samba clients it uses the builtin "du" command of smbclient (if
your smbclient version is recent enough).
