Which industry and best how?

'Cause I could apply some pretty heavy snark to that statement, if I wanted to:

The White House has acknowledged recycling its backup computer tapes of e-mail before October 2003, raising the possibility that many electronic messages — including those pertaining to the CIA leak case — have been taped over and are gone forever.

The disclosure came minutes before midnight Tuesday under a court-ordered deadline that forced the White House to reveal information it has previously refused to provide.

Among the e-mails that could be lost are messages swapped by any White House officials involved in discussions about leaking the identity of CIA officer Valerie Plame.

Before October 2003, the White House recycled its backup tapes "consistent with industry best practices," according to a sworn statement by a White House aide.
