did you consider, or has anybody else used Chronosync for this? Is Chronosync equally effective as Arq? I suppose depends on whether it uses a snapshot-style backup and Chronosync does have an option in its backup options and I have enabled that option. From Chronosync options description:
Freeze file system - If snapshots are supported and this option is turned ON, a snapshot of your file system will be taken before running the task and then used as your source target.
While I did purchase Arq, and have used it, I would rather not have the Arq files at the other end.
Thank you.
