Keeping 6 months of deleted files before permanent deletion?

[lovelyjubbly]

I have a Source on a PC that I'd like to backup to a Target on a Synology NAS.

I have the FreeFileSync Donation version.

I'd like to backup everything from the Source to the Target every hour or so.

If I delete something in the Source I'd like it to remain in the Target for 6 months, before it gets deleted for good.

Is this possible?

Many thanks.

You can use Versioning.
This will move all files to be deleted or replaced during an FFS sync to a specified location in its existing (sub)folder structure.
You can also Limit File Versions according to need. See the right-bottom part of the image in said manual section. This includes an option to delete versions after x days, where in your case x would be 183.

Thanks Plerry, I'm working my way through versioning at the moment, I'll report back once I've tested it thoroughly.
