If data integrity is important, is TFM Backup enough or is rsync better?

Our system does perform checksum verification for backup results.

RyanYang, just to be clear, is this with regards to TFM Backup or were you referring to Rsync Backup?

During our laboratory testing procedures, we specifically verify file integrity by checking MD5 values to ensure data consistency.

So was this human testing, or was the system checking with copying? The way I read your message it's human's verified, but maybe I read it wrong. Just want to be clear on this.

Hello, currently both our TFM and Rsync Backup perform integrity checks on the backup results.

However, we are continuously working to optimize the verification methods. Since there is a natural trade-off between data verification and backup speed, the current verification algorithm does not yet achieve absolute perfection — it is a balance between the two. In the future, we will continue to explore more advanced and reliable solutions.

Maybe the degree of verification in future version(s) could be an optional choice so the user/admin can make that decision for themselves.

This solution is indeed one of the options we are considering. However, choosing a lightweight verification algorithm is equally important. We will conduct a comprehensive evaluation within our team. Thank you very much for your suggestion!
