[Help please] What is a good free, open-source, or low-cost computer backup program?

My hard drive size is roughly 3.5Tb (out of 6Tb total size). It won't get much bigger. I use a 5TB portable hard drive for backups.

I am looking for a file backup program that can backup new or changed files, and won't need to clone the entire hard drive again for each backup, as this process takes hours and hours.

Any suggestions appreciated.

Thanks peeps :marseyblowkiss:

Can also use rsync with btrfs compression if you want backup compression with no need to destroy your rsync workflow with archives

If you're using btrfs you'd just use snapshots for send and receive. No need for rsync.

Not sure if by compression you mean gzip or something?

Unless you're using a very very small network pipe I wouldn't bother with rsync compression unless you know the files you're sending are compressible - basically text files or documents.
