      I wish to perform a daily delta backup and a monthly full backup, as shown below:

      Does this mean the daily chain will be reset after each monthly?

      i.e. On 2nd the chain will be Monthly Full + Daily Delta

        @McHenry the second pattern 0 20 1 * * reads as At 8PM on the first day of the month run your full backup.

        The first is to run a delta at the same time every day of the month, besides the first of the month.

          Does this mean the daily delta chain will be reset on the 1st of each month when a full backup is performed?

            To my experience, no. There will always be 31 deltas
            After a few month's it can look like this:
            MMMddddddddddddddddddddMddddddddddd

              Thank you but still not 100% clear.

              As we want to reset the delta chain periodically with a full backup, does the monthly full backup achieve this goal?

              My question is ultimately, what is the maximum length of the delta chain in this scenario?

                I don't know offhand if the full then creates new delta's from that point forward, as I recall the delta depth is pretty damn good (I've never had to restore from a full).

                Maybe someone from the vates team will pop in and know the answer.

                    Please don't ping me directly, I can't clone myself 🙂 And no, I can't clarify, I don't have time right now. Maybe @lsouai-vates can 🙂
