Incremental backups are not possible because of frequent backfilling

Occasional back filling of data would cause 5 TB of archives to be backed up with incremental backups. This is frustrating because only a few KB of data is changed in each archive. Can OSIsoft provide a way to backup only the data that has changed or support a 3rd party backup solution that would backup only the differences?

    This issue could be alleviated with the creation of different archives sets https://pisystem.feedback.aveva.com/ideas/PIDA-I-1183 (related). This would allow users to have an archive set for process data that would never need to have any backfills and another archive set for analytics.

    you give people the power to make analyses in AF along with the capability of backfilling . . . of course they are going to be in there backfilling years worth of data every time they make a new analysis. Anytime anyone asks for a new piece of data (calculation or not) . . . they will always want the history of that data point . . . so on AF analyses that requires backfilling. . . . and next day/week/month they will realize some additional item to put in their analysis and make the edit and backfill for all those years all over again again
