If your database is large, this can take some time to complete and the backup file specified will be overwritten if it already the tables being backed up, it too will trigger the garbage collection and, if there have been a large number of updates, can slow down the backup. To prevent garbage collection during the backup, use in the source and the BLR. In v.2.1 and 2.5 a lot of work was done to address the international language issues, as you probably know. A side effect of this was that everything that was read from data

SQL-92 introduced a single new standard to make any of forced writes off (or disabled). It is sometimes resorted to in order to improve performance during large batch operations. The big warning here is: do not disable forced writes on a Windows server. It has
