Unless you are checksumming your files through a daemon run on a schedule (IDS style) AND manually review the results every now and then, you can't know.
- uselpa 3y agoIf you have versioned backups, you can diff against update_day-1 without an additional tool.
- csdvrx 3y agoI have versioned backups for a few months. Most people don't and can't (it requires a lot of storage) Even if they have them, the diffing needs to be done. Given the past problems with ZFS, I think I'll write a summarizer, that creates a database of metadata for each backup: it will be small to keep around, and may be use more easily to determine which backup contains the uncorrupted file.
- uselpa 3y agoI use borgbackup so the storage requirements are fairly low if the data does not change too much (which is my case). Also diffs are just a « borg diff » away.
