I'd use a variable for that. When you detect files, change the variable, and it'll stay changed.

find may be more efficient than ls | grep.

Code:
trap "rm -f /tmp/$$" EXIT
INTERVAL=300

while true
do
        find /mydir -uname root '!' -path 'lost+found' > /tmp/$$
        # If the file is not empty, set the interval to 10
        [ -s /tmp/$$ ] || INTERVAL=10
        cat /tmp/$$
        sleep $INTERVAL
done

amverify

AMVERIFY(8)						      System Manager's Manual						       AMVERIFY(8)

NAME

       amverify - check an Amanda tape for errors

SYNOPSIS

       amverify config [ slot [ runtapes ] ]

DESCRIPTION

       Amverify  reads	an  Amanda  format  tape  and makes sure each backup image can be processed by amrestore and, if possible, the appropriate
       restore program (e.g. tar).

       Amverify runs amrestore on each file of the tape and pipes the output to a restore program (if available) with an option to create a  cata-
       logue of the backup.  The catalogue itself is discarded.  Only the success or failure of the operation itself is reported.

       If  the	backup image cannot be processed by the restore program, e.g. if it was written on a different operating system, the image is sent
       through dd to /dev/null.  This still determines if the tape is readable, but does not do any internal consistency check on the image.

       If config is set up to use a tape changer, the slot argument may be used to choose the first tape to process.  Otherwise, the current  slot
       is used.

       The runtapes configuration parameter determines how many tapes are processed unless it is specified on the command line.

       See the amanda(8) man page for more details about Amanda.
