We ran regularly three kind of backups: Daily (which are incrementals), Weekly (performed on Saturday night) and monthly(on the 30th of the month). Daily backups are protected for a week, weekly backups for a month and monthly backups for a year. In case of a DRP or if a file was deletd or damaged and needs to be restored, which is the best strategy for keeping backup tapes locally? Which should be kept at the office? Which must be sent to 3rd party storage? Thanks.
