#
# backup-2.*: Test backup under various conditions. To and from in-memory
# databases. To and from empty/populated databases. etc.
#
# backup-3.*: Verify that the locking-page (pending byte page) is handled.
#
# backup-4.*: Test various error conditions.
#
# backup-5.*: Test the source database being modified during a backup.
#
# backup-6.*: Test the backup_remaining() and backup_pagecount() APIs.

# backup-7.*: Test SQLITE_BUSY and SQLITE_LOCKED errors.
#
# backup-8.*: Test multiple simultaneous backup operations.
#
# backup-9.*: Test that passing a negative argument to backup_step() is
# interpreted as "copy the whole file".

# backup-5.x.2.*: Modify the database mid-backup so that one or more

#
# backup-5.x.3.*: Database is vacuumed.
#
# backup-5.x.4.*: Database is vacuumed and the page-size modified.

# Each test is run three times, in the following configurations:

# 1) Backing up file-to-file. The writer writes via an external pager.
# 2) Backing up file-to-file. The writer writes via the same pager as
