due to current high price of hdds, I would like to switch from running RAID1 to JBOD + offsite backup (Backblaze). In theory it's a much better approach (if PC gets fried by lighting strike, I still retain all my data), but in practice it will make me vulnerable to file corruption issues (Backblaze will silently replicate all changes and erase past versions after 30 days).
Do you know of any program, that run checksums on all my files and compare them to "Modified:" timestamp (I'm assuming that all hash changes without modified timestamp chnage would indicate file corruption)?

1Please tell me you are aware that RAID1 and Backup solve different problems, and best practice is to use both. RAID1 provides protection against single hard drive failure - NOT DATA CORRUPTION while backup is supposed to prevent against data corruption, accidental deletion, theft etc). Really, hard drive space is dirt cheap for what it is, and relative to everything else in your PC. Also, for backups, depending on what you are doing, best practice is to use versioning software, failing which incremental backups or snapshots. – davidgo – 2013-03-09T22:44:53.310
