Eric, Just noticed your question was about circular logging....
"The customer uses circular logging only for all Domino instances." With circular logging, we cannot backup transaction logs! Anyway YES, Daily incrementals instead of Daily selectives with occasional incremental is fine. New and changed nsf files will be backed up, deleted ones will be inactivated... ====================================================================================================== This topic is found under "Backup Strategies" in the book. http://www-01.ibm.com/support/knowledgecenter/SSGSG7_7.1.0/com.ibm.itsm.mail.dom.win.doc/concept_domcbup3.html Sample Strategies ... Full backup plus transaction log archives It is often not practical to back up entire databases with each regular backup for large Domino installations. Archival logging captures changes to all logged databases in the archived transaction log files. Full database backups are run less frequently, reducing burdens on network and storage resources. To implement this strategy: - Run regular log archives by running the archivelog command. The log file does not fill and it captures changes to logged databases. - Run regular Incremental backups, which back up logged databases with unchanged DBIIDs. - Run occasional Selective backups of all logged databases. The number of transaction log files to be processed during a restore is reduced. - Issue the inarchivelog command (following Selective backups) to allow nonessential transaction log files to expire. The archivelog command captures changes to all logged databases in between full backups of selected databases. To restore a database to its most recent state, restore the most recent database backup and specify /applylogs. All the necessary archived transaction log files are restored so that updates for the database can be applied From: "Loon, EJ van (ITOPT3) - KLM" <eric-van.l...@klm.com> To: ADSM-L@VM.MARIST.EDU Date: 08/21/2015 09:00 AM Subject: Data Protection for IBM Domino Sent by: "ADSM: Dist Stor Manager" <ADSM-L@VM.MARIST.EDU> Hi guys! One of my customers uses Data Protection for IBM Domino for a few years now. All mail instances are backed up daily with the domdsmc selective command. I recently discovered that old deleted databases were never removed from TSM, which seems to be caused by the fact that we do selectives only. Only an occasional domdsmc incremental seems to remove them. So I recommended the customer to implement an incremental backup once a week. He now asks me "What if I run daily incrementals instead of the selectives?" I don't know if that will work, nor can I find the answer in the manuals... The customer uses circular logging only for all Domino instances. Thank you very much for your help in advance!
