Hi folks,

Here's the scenario:
1. 12:00 AM - Full or Diff backup
2. every 15 minutes t-logs backup (logs are stored to the recent backup file of either the full or diff)
3. after the full or diff backup our network guy backup the files from the disk to tape

While doing the backup from disk to tape, the file being backup is also being updated via the tlogs backup. What will happen to the file that is being backup on to tape while also the same file being used to store the t-logs backup

Hope others could shed light and share their approaches in backing up db files backup to tape.

Kindest regard,

It should be locked.

I always back up to seperate files for each backup. Then if a file is corrupt or lost you only lose one backup.

Cursors are useful if you don't know sql.
DTS can be used in a similar way.

Thanks NR. I guess my problem now is how to backup t-logs files to tape without losing t-logs due to locking of files.

Kindest regard,

You could backup to one folder and then MOVE to another folder to backup. The standard Command Line MOVE will not move a file that is open - so that one will get moved on the next hourly run, etc.
