sybase自動備份的方法我們經常會用到,下面就為您詳細介紹sybase自動備份的實現過程,希望對您學習sybase自動備份方面能有所幫助。
- Imports System.IO
- Module Module1
- Sub Main()
- Dim str_Path As String
- Dim str_FileName As String
- Dim str_Name As String
- Dim i As Integer, weeknum As Integer
- Dim f_file As System.IO.File
- Dim F_write As System.IO.StreamWriter
- Dim str_temp As String
- str_FileName = gbackupdump_data.txt
- If File.Exists(str_FileName) = True Then
- File.Delete(str_FileName)
- End If
- F_write = File.CreateText(str_FileName)
- F_write.WriteLine(use master)
- F_write.WriteLine(go)
- weeknum = Weekday(Now())
- '每隔一天轉儲的文件名相同
- Select Case weeknum
- Case 1, 2, 4, 6
- F_write.WriteLine(select getdate())
- F_write.WriteLine(go)
- F_write.WriteLine(dump database bsjdw to 'g:\backup\dumpback\bsjdw_data0.dump')
- F_write.WriteLine(go)
- F_write.WriteLine(select getdate())
- F_write.WriteLine(go)
- F_write.WriteLine(dump database system to 'g:\backup\dumpbacksystem_data0.dump')
- F_write.WriteLine(go)
- F_write.WriteLine(select getdate())
- F_write.WriteLine(go)
- Case 3, 5, 7
- F_write.WriteLine(select getdate())
- F_write.WriteLine(go)
- F_write.WriteLine(dump database bsjdw to 'g:\backupdumpbackbsjdw_data1.dump')
- F_write.WriteLine(go)
- F_write.WriteLine(select getdate())
- F_write.WriteLine(go)
- F_write.WriteLine(dump database system to 'gbackupdumpbacksystem_data1.dump')
- F_write.WriteLine(go)
- F_write.WriteLine(select getdate())
- F_write.WriteLine(go)
- End Select
- F_write.WriteLine(exit)
- F_write.Close()
- Dim ti As Date
- Dim te As Date
- ti = Now
- Dim logfilename As String
- logfilename = datafile + Trim(Str(Year(Now()))) + Trim(Str(Month(Now()))) + Trim(Str(Day(Now()))) + .txt
- Shell(cmd k isql -Usa -PSjb81! -i + str_FileName +gbackupdumpbackdumplog + logfilename, AppWinStyle.NormalFocus)
- te = Now
- Try
- Dim myProcesses() As Process
