Can someone explain difference between retention range and expiry tolerance? I have 2 long term recovery goals,
1. Weekly backup expire after 4 weeks.
2. Monthly backup expire after 3 months.
Now what role expiry tolerance parameter does play here..!! and what should be the right value of this.
Honestly, I dont have idea about expiry tolerance, so i have set Tapewriteperiod to 1 month and expiry tolerance to 5 years because i have been asked to set retention 5 years. (this is co located PG)
I am going to change recovery goal 2, from 3 months to 5 years retention. So where should I made changes? on expiry tolerance or retention range?.
one more thing I want to mark tapes 'offsite ready' when they full written. As there is not percentage ratio option available in DPM 2012, what would be the 'tapewriteperiod' value for 3 months or 5 years retention to full utilize these tapes.
