Hello folks,

For my Linux server backups, i really love BorgBackup but i'm looking now for something that natively support S3. I've heard few good things about Kopia and feel like it's the way i may go. I would prefer something free so Duplicacy, which i use and like a lot for my home personnal usage, is not an option. I also want to use encryption, compression and dedup.

What do you use for your backups that support S3 as backend?

On the side i've read few discussions regarding encryption methods, looks like some use good encryption, some others use double encryption which sounds a bad idea (and also use of OpenSSL) regarding some people with security interest, some use also homemade encryption while there is existing good encryption algorithms. I'm not that used to advanced security like that but as most of us i try to make the best choices for long term use.

In the past i've used a lot BackupPC. Useful frontend when your team is not that advanced with SSH, you can keep the compression locally to the BackupPC server even if you get file from remote, etc.

What's your input?

Thanks a lot for all your advices and app sharing!
