What are the most secure options for backup?

[GPaul]

I devoted the last two months for similar considerations and searching for the best backup program for me.
So I will briefly share my end conclusions.

Duplicity has a lot of options both for backup and for restore, so how do I make it the best way?

Duplicity has disadvantages that threw him for me from my list:

• No deduplication
• only the main copy + incremental copies = failure of any previous intermediate copy causes that others become useless

Do you want your backup to be in native format? (In other words, the backup data looks exactly like the source data.) If so, Duplicati won’t be the right tool.

The reason the backup files look different is because all data is run through a deduplication engine, gets compressed, and then optionally encrypted. What this gets you is efficient storage of multiple backup versions. What you lose is the files aren’t stored in native format, and you must go through the restore process to get back the original files.

If you’re still open to using Duplicati, might I suggest what I did when I was new to it: configure a small back up job on your most important data and use it for a while so you get comfortable with it.

Vorta (GUI for Borg) can mount the pointed backup as an ordinary folder for browsing

Considering Duplicati is technically in beta and also has some not so good code issues, on top of trying to backup 2TB this way, personally I wouldn’t use it in that situation.

I am exactly the same opinion.
I have a fondness for Duplicati and I will watch it, but until I stabilize its code, I can not use it
Here, an additional topic: Is Duplicati 2 ready for production?
The thread is old, but at some point jumps to newer times.

I am sorry that I will not describe everything in detail and all the tests, but I miss time for this
Short:
With about ten programs I chose two and now I will test in parallel for a few months: Vorta + Kopia.io
For me important features: deduplication + encryption + authentication + compression + Mounting FUSE + GUI
Tests carried out on 6TB data

Duplicati will look at and waited for a stable code.
