Compression

[piombo]

I'm using Meteohub since 2008 and my 4 GB SD-Card is getting full.
The solve this problem I see two possibilities:
a) moving raw-data somewhere else (+) free space, faster recalculation after e.g. data-correction (-) can't access this data anymore with Meteohub
b) getting a larger sd-card (+) all data accessible (-) very long recalculation-time

Would it be possible to compress older data which uses a big amount of space (e.g. everything older than 3 years)? Meteohub could decompress the data when needed (which doesn't happen often).
Is it necessary to recalculate all the data? There shouldn't be any changes in older data.

Do others have similar problems or is there a solution that I don't see?

Thanks.
