SQL Server restore differential without original full backup -


here situation: had full backup, , differential backup. have restored full backup database. accidentally lost backup file.

now apply differential backup. must restore both full backup, , differential, without opening db use (norecovery option). however, have opened db, not made updates.

we have made new full backup, should identical original full backup, except @ least timestamp. is, sql server detects differential not taken db full backup.

is there way trick sql server allowing differential work new full backup? (i realize risky, data important , willing risk errors.)

is there other way updates out of differential backup applied manually? there "decoder" differential backup file? special recovery tools kind of situation?

you can try restoring diff. norecovery mode:

restore database diff_db disk='m:\diff_db.bak' norecovery

then bring database online running below 

restore database diff_db recovery

if doesn't helpful can try alternate solution sql backup recovery tool database.
