Looking for download/update metadata library manually

[stanmarsh]

Hello MobileRead Community,

im looking for a way to download metadata of library while im away from home, and just update the metadata when im at home.

the idea is like this using calibre portable,
away from home
1. copy the database of your library
2. restore database in calibre
3. download metadata
4. export downloaded metadata to file
5. exit calibre

at home
1. open calibre
2. import downloaded metadata file
3. once imported this is the only time that calibre will rename/move folder/files
4. exit calibre

any suggestion / comments?

TIA
