Excluding /Library/Sophos Anti-Virus/ from Time Machine backups

Whenever Sophos AV gets updated and that's more than once a day the files in the folder /Library/Sophos Anti-Virus/ are modified, this in turn makes Time Machine backup around 60 MB to 100 MB of virus definitions everytime it runs. This fills my Time Machine disk with useless versions of virus definition files.

So my idea is to exclude the /Library/Sophos Anti-Virus/ folder, but how safe is it? Does Sophos AV automatically recreate it and download the files if the folder is missing? Specifically, if I have to restore my whole system from a time machine backup without the VDL folder, how will Sophos AV handle the situation?

What I would really like to see would be Sophos AV excluding VDL files automatically from backup and have in place a routine that would refetch all needed files that were not backed up. 

[Edited to change /Library/Sophos Anti-Virus/ VDL to /Library/Sophos Anti-Virus/ since not only the VDL dir is updated]

  • The VDL files are generated by the engine itself, based on the data downloaded and what's in the cache.  If the caches are also purged, it'll just mean more data gets downloaded in the update.  Other than the larger monthly updates and the product version updates, the incremental  downloaded updates should be only a few MB and installed to the IDE folder.
