Database Log Files


Recommended Posts

I've been pondering this one a few hours, and there has to be an easier way to do it. Here's what has to be done:

Let's say directory "A" has database log (like binary log) files.

Directory "B" is my backup directory.

I want to copy anything that is in A to B. Pretty easy with:

FileCopy($s_DBFolder & "\*.log", $s_HourlyFolder, 0)

... but then I want to maintain X days of log files past the oldest file in "A" in "B" for emergencies.

I thought about things like creating an array with FileFindNextFile and all sorts of horrible solutions, but there are potentially thousands of files and there has to be a better way.

Any ideas on the best way to attack this?

Personally, I like the _FileListToArray() command for getting a list of files from a folder :D

Then all you have to do is compare the FileGetTime() of the last file in A to the files in B and see if it's within your timeframe.

I did not see that function, I'll give it a look, thanks. I was thinking I'd have to write that part, much better to use something existing. :D

Can we be certain that the last file is actually the oldest file?

I would read A to an array using the same function, the using the FileGetTime, loop through the array checking to see if the next file is older. Durring each loop, if the file with the older time is assigned to a variable, then by the end of the loop, you should have the oldest file in there.

Something like:

$array = _FileListToArray("C:FolderA", "*", 1);1 to return files only
$oldtime = @YEAR&@MON&@MDAY&@HOUR&@MIN&@SEC
For $i = 1 to Ubound($array)-1
 $aTime = FileGetTime("C:FolderA" & $array[$i], 0, 1);0 is the last modified time, 1 returns the time in YYYYMMDDHHMMSS format
 If $aTime < $oldtime Then
  $oldtime = $aTime
  $oldfile = $array[$i]
 EndIf
Next

Aha! The old bubble sort! great call, thanks for kiling my gray matter into firing on all cylinders. :D
