REM backup mssql db

C:\mssql_backup\expressmaint.exe -S TEST -U sa -P testing -D TESTING -T DB -R C:\mssql_backup\log  -RU minutes -RV 3 ^
                                                         -B C:\mssql_backup\db -BU minutes -BV 3 -BF  $(DB)_$(DATE)_$(TIME)_$(OPTYPE) -V

C:\mssql_backup\expressmaint.exe -S TEST -U sa -P testing -D TESTING -T LOG -R C:\mssql_backup\log  -RU minutes -RV 3 ^
                                                          -B C:\mssql_backup\db -BU minutes -BV 3 -BF   $(DB)_$(DATE)_$(TIME)_$(OPTYPE) -V

Output:

TESTING_FullBackup_20120307_1225
TESTING_LogBackup_20120307_1225

P.S.

假設每 min backup 一次

min  20    21     22        X        X       25  <-- 在 25min 的 backup 會 Delete 22,21,22 分的 backup !!!!
        bu    bu     bu     miss   miss     bu

所以當幾次 backup 失敗後再 backup, 記得移開要保留的 Backup 先 !!
