INF: Differential Backup Time ConsiderationsID: Q196658
|
A differential backup only records changes made to the database since the
last full backup was made. While typically much faster than a full database
backup, elapsed time for SQL Server 7.0 differential backup is roughly
proportional to the allocated space in the database. Consequently, a
differential backup on a very large database may take longer than expected,
even if few changes have occurred since the last full database backup.
If the amount of time required for a differential backup is too large, you
should consider doing log backups instead.
