Ideas on most efficient way to clone duplicacy backup to external drive

Support
#1

Hi all,

I have been using and loving Duplicacy for about 12 months now. The best backup solution for my needs - so glad I found it.

I use it to backup a bunch of data from a desktop to a QNAP. I then use FreeFileSync to periodically mirror the Duplicacy backed up data from the QNAP to a pair of external hard drives for additional copies / protection.

This method takes ages and keeps all the drives really busy (more wear?) as it needs to check all files from the source and destination before it can update the external to make it an exact copy.

Is there are a faster / more efficient way to do this, perhaps something taking advantage of the immutability properties of the Duplicacy specification?

Any advice appreciated.

Thanks!

duplicacy copy would be better. Initialize two new storage locations on each drive, and then run duplicacy copy command from main repository to the target whenever each target is connected.

I however strongly suggest not using external drives for backup. Instead, periodically copy your backup to some cloud storage.

Thanks saspus, really appreciate the advice.

I have cloud backups as well of my most important data. However, my internet connection is not particularly fast so would take AGES to copy all my backed up data to the cloud, not to mention updates.

The external drives are to provide onsite redundancy so I can get back up and running quickly if there is a failure.

I will give the duplicacy copy command a go. If all else fails I guess I will continue the freefilesync mirroring I am currently doing as it does seem to work, albeit a bit slower.

Thanks again.
