Disable time check on a per file basis

opened 01:02PM - 03 Sep 24 UTC

Further discussion here https://forum.duplicati.com/t/disable-time-check-on-a-p…er-file-basis It would be good to enable the ability to disable the file check on a per file or filter-like expression basis so that the entire backup job doesn't take longer than needed if only some files need a time check to successfully back up. In "Advanced Options" disable-filetime-check already exists but this is for the complete set. It would be good to have the option of something like --disable-filetime-check-include=*.iso and/or --disable-filetime-check-include=/path/to/file

but as it turns out, there was this one a few days earlier. I don’t know if it was forum-inspired.

Have a list of mountable filetypes that don't change timestamps on edit.

**Is your feature request related to a problem? Please describe.** When a VeraC…rypt hc file (probably same for TrueCrypt tc with less secure enryption) is mounted, file(s) edited & saved, then unmounted, the timestamp is not changed by VeraCrypt. Duplicati does not make an incremental backup. **Describe the solution you'd like** - If such a file type is found, do binary comparison (not just date & size comparison). A fast algorithm is here: https://stackoverflow.com/a/1359947 (exit early on diff, quite fast on 1 GB hc file). - Do the extra check for hc or tc file (and possibly other types that may have concerns, but I don't now of any others). **Describe alternatives you've considered** - use custom program do backup this one file (I do this now, but it is not ideal and is not integrated with Duplicati) - submitting issue to VeraCrypt (not ideal since some people never update and therefore will always have the issue, but I may do that)
