The word "easier" was an unfortunate choice...
I meant to indicate that an incremental backup (e.g. a few hundred
files) is "in some ways" more convenient than doing a new backup of a
100GB database.
Our images is never (well, hardly ever) changed. Images just get
added. Which means that incremental backups are fast (and
affordable). Moving a 100GB backup to tape every night is another matter.
Even so, I'm heading for the database solution!
