Back up a user database after the following events:
After creating it, to develop a baseline backup. Thereafter, back up each database on a fixed schedule. Daily backups of the transaction log and weekly database backups are the minimum recommended. Many installations with large and active databases make transaction log dumps every half hour or hour and database dumps every day.
After creating a new index. The transaction log records the create index transaction but does not log the filling of index pages with information.
After executing the following unlogged transactions:
Unlogged writetext
select into on a permanent table
Bulk copy in “fast” mode (bcp into a table with no triggers or indexes)
After truncating the transaction log without making a backup copy.
