backup : files being modified while tarring

I would like to back up several directories weekly using a cronjob.

I'm not experienced in UNIX, but I would start like this:

tar -cvf backup.tar dir1 dir2 dir3

Now if a file is being modified in the process it will result in an error.

How can I prevent this from happening and how can I determine if the backup has been succesful ?

WEEKLY(5)						      BSD File Formats Manual							 WEEKLY(5)

NAME
weekly, weekly.conf -- weekly maintenance DESCRIPTION
The /etc/weekly script is run, by default, every Saturday morning on a NetBSD system. The /etc/weekly.conf file specifies which of the stan- dard weekly services are performed. The variables described below can be set to ``YES'' or ``NO'' in the /etc/weekly.conf file. The default settings are in the /etc/defaults/weekly.conf file. (Note that you should never edit /etc/defaults/weekly.conf directly, as it is often replaced during system upgrades.) rebuild_locatedb This rebuilds the locate(1) database, /var/db/locate.database, which must also exist, in order to be rebuilt. rebuild_mandb This rebuilds the apropos(1) database /var/db/man.db, using makemandb(8) with the -f option. rebuild_whatisdb This rebuilds the whatis(1) database(s). Note that NetBSD provides a default whatis.db for the system manual pages and this may not be needed. (Adjust your /etc/man.conf as necessary; see man.conf(5) for details.) FILES
/etc/weekly weekly maintenance script /etc/weekly.conf weekly maintenance configuration /etc/weekly.local local site additions to /etc/weekly SEE ALSO
