Hello Christopher,
My incremental backup went fine and upto 1 limit it has resolved my issue as well as after incremental backup my data changes in size has reduced to 50GB from earlier size of 120GB when I was taking full backup.
Now I am trying to take incremental backup for another 4 days and then go for a full backup. At that point of time this solution will work for me if data changes size is less than 150GB with full backup. It it remain so then I will be able to replicate my these backups also in 2 days of weekend but if it goes something more 150GB then i need to look for some other solution. :-(
Now transfering the IDB is not a big deal in my case, what I am doing is restoring an IDB from recent backup and put this IDB on the same drive "H Drive" where I have storeOnce library and replicate it to DR with the backup. Then at DR end stop the DP services on DR CM, copy new IDB from production (which will be now availaible in "H drive" of DR MSA), change CM name and finish. At this point I am able to restore my data at DR.
Now my finger is crossed only to see how much data changes is there when I am going to take full backup using StoreOnce software deduplication after 5 days.
Regards,
Syed
