There is or was an 'issue' with NDMP where the dump levels for incrementals rolled past 9 and went back to 0, causing a full and it would stay at dump level 0 until the next scheduled full ran. I cannot find a technote or any documentation on it, but I believe it was related to cumulative incs only (since that is dump level 2-9) and a schedule where the cumulatives were set to run more than the available dump levels. So the first 8 days you would be ok, but on the ninth and subesquent cumulative inc days you got a full.
I am not sure if this ever got fixed or not and we experienced this with NBU 5.1 probably 3-4 years ago. Rusty Major, MCSE, BCFP, VCS ▪ Sr. Storage Engineer ▪ SunGard Availability Services ▪ 757 N.

However, when he checks for the block changes in Netapp console,it reports block changes amounting to 60GB I was of the impression that NDMP incrementals happen at the block level, in which case his incremental size had to be around 60GB. Can someone explain to me why this is so. Appreciate if you could get down to nuts and bolts and tell me how NDMP treats incrementals/level backups. dp_nash +---------------------------------------------------------------------- |This was sent by n_ash...@yahoo.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +---------------------------------------------------------------------- _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
