With TDP products, in some cases, the backup objects are given different, unique names every time a backup occurs -- you must review the Install & User's Guide for the TDP you are using. For example, TDP v1 for Exchange creates unique names for every backup, so retention/expiration must be done manually; in v2 of this TDP, objects stored in backup storage are given the same name, so their retention/expiration becomes "automated" like for files backed up by the b/a-client -- and the management class rules, as I described, will apply. Hope this helps. ----- Original Message ----- From: "Regelin Michael (CHA)" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, May 03, 2002 5:17 AM Subject: Re: Help Understanding Mgmt classes Hi Don, I'm not sure to understand your answer. By the way, thanks for your answer. I'm interested in this mailing and was not the originator. Our Backup solution is based on tdp for domino 1.1.2. Our tsm client is 4.2.1.20 based on Windows Nt4 server. here is our strategy: a full backup a week - keeping 5 version (management class=week) a full backup a month - keeping 13 version (management class=month) an incremental version a day - keeping 5 version (management class=daily) after reading your mail, I understand that having 3 MC for the same file will cause the retention to change after every backup when the MC is used. So for example: when week backup is finished, it will apply the MC for the file and when month backup is finished, it will change all retention on every file base on the new MC ? thanks Mike > ____________________________________________________________________________ _______ > Michael REGELIN > Inginieur Informatique - O.S.O. > Groupware & Messagerie > Centre des Technologies de l'Information (CTI) > Route des Acacias 82 > CP149 - 1211 Genhve 8 > Til. + 41 22 3274322 - Fax + 41 22 3275499 > Mailto:[EMAIL PROTECTED] > http://intraCTI.etat-ge.ch/services_complementaires/messagerie.html > __________________________________________________________ > -----Message d'origine----- De : Don France (TSMnews) [mailto:[EMAIL PROTECTED]] Envoyi : vendredi, 3. mai 2002 03:39 @ : [EMAIL PROTECTED] Objet : Re: Help Understanding Mgmt classes You are abit confused. The *ONLY* way to have TWO policies applicable to a given file is to use TWO node-names for your backups; swapping policy sets *may* work for your situation, if what you want (and set) is 30 versions of a given file... that piece will work. Files can be bound only to one management class at a time; if you try changing MC for the file, it will change ALL versions to that MC, not just the next backup. The policyset-swap trick is useful when changing from modified to absolute and back; that's about the only use I've ever seen for multiple policy sets. Hope this helps.
