Richard, As is so often the case - It depends.
For volume backups 14 days does give you a fall back in the event of a bad tape. For HSM alternate tapes, these need to exist as long as the primary backup/ML2 tapes exist. If the 180 day backup contains the only backup for a given file, it might be very valuable. If you're only referring to full volume backups taken weekly then probably it is of very little value.

Obviously, in a coop situation, one would use the most current backup tape but how many versions of backup tapes need to be kept and when is a tape too old to be of any value? For example, of what value is a backup tape that is 180 days old? I suspect the answers we vary depending on the type of business, etc. but any input will be appreciated. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
