I switched from TIH 2014 where I was using an incremental back-up scheme for my data files. This scheme was (full backup + 5 incremental backups) repeating for a month, at which point the oldest backups were deleted and replaces with new backups. I suspect that one could produce a script to do something like this in my new DHM 15, but I am not sufficiently knowledgeable to do it. I wonder is someone has developed a script at least for the first element of the chain (1 full backup + X incremental backups + stop) or for a non-reoccurring chain (1st set followed 2nd, 3rd, etc. sets without removing the old sets). If you have something like this, please share it with people like me who cannot write a script. Thanks.
Look for "Paragon Retention Wizard" on the Internet. It is unclear how Paragon distribute it. Previously (up to HDM14) it was addon to HDM_Pro, now with HDM_15 it is not, although it works.
