When doing transaction log backups, is it best practice to just keep appending to the same file or creating a new .trn file for each backup?

This question came from our site for professional and enthusiast programmers.

Which RDBMS are you working with? By your transaction log backup file extension I'm guessing SQL Server..? – Thomas Stringer Feb 9 '13 at 1:26

I personally create a whole new NTFS file for each backup. Why? Because there is no chance of accidentally overwriting a backup (with init). A lost transaction log backup is crippling. In my opinion, the maintenance overhead of multiple backup devices/files is negligible.
