I've been thinking how to phrase a sentence. I meant to say we will back up a copy daily. If today is Thursday, we have an archive of Monday, Tuesday and Wednesday. If today is Sunday, we have a copy of Thurs, Fri and Sat.

Does any of the following sound appropriate?

Daily backup and archive up to 3 recent days

Daily backup and archive the last 3 days

I think the first sentence construction is not right. I googled but I don't see any sentence examples using numbers before recent days.

I'm not too sure if the second sentence is conveying the meaning correctly.

I'm cracking my brain not sure how to phrase the sentence correctly.

First, I would rephrase "Daily backup" to "Backup daily" since the more common construction of a command is verb + adverb, not the other way around. "Daily backup" is too easily read as a noun--which it is--as in, "Have you done your daily backup today?"

Second, up to 3 recent days is not idiomatic, which is why you don't find examples in your Google search. To improve the first example, you could write:

Backup daily and archive the three most recent days.

The second example is better, and will work fine if you simply reverse "daily" and "backup":

Backup daily and archive [or keep an archive of] the last three days.


I have upvoted Rob Jarvis’s answer. However, if we go beyond the original question of what is “proper” into what will most easily be understood by the most people, I would change the vocabulary.

Make a back-up copy daily and keep it until four days after it was made.
