This is true of any physical backup mechanism though. Whether it's drives, tapes, etc., it will be an added expense and off-site storage will be an additional hassle. A network backup of files, either to a cloud or to an external system elsewhere, replaces the effort of transporting media and up-front cost of backup drives/etc. with a bandwidth cost and some sort of recurring cost. Depending on the amount of data that changes, the way the backup mechanism works, etc., this may not be feasible in some cases. This also requires trusting the cloud provider/external system/etc. with your data. --CAE _______________________________________________ Discuss mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
