"Dominique Willems" | One of my smarter customers has managed to end a process (via task
manager) that was in the middle of optimizing a table, containing a huge blob file. He mailed me complaining that alot of data seems to have disappeared after his stunt. The bad news is that he restarted the application after ending it, which caused it to overwrite the .bbk, .dbk, and .ibk backups again with the bad files, since it restarted the optimizing process. I know the man himself is not to be helped, but can any of the data be recovered? Many thanks. PS: using 3.30 -- |

"Iztok Lajovic" | Dominique,
I don't know how to recover files corrupted in that way. This situation could force you to think about procedure for daily backups incorporated in your application that makes every time new backup. New backup should overwrite the oldest in a list of, let say, 10 backups. In that case the user could restore any backup from the list.

That's been built-in for over a decade, but he has to click the button. ![]() -- |

I took a look at his table, deleted a few odd rows, applied a repair, then an optimize, and all is dandy. That's DBISAM for you. Never a bit lost in its entire career. ![]() -- |

I'm glad that you were able to recover everything okay. << That's DBISAM for you. Never a bit lost in its entire career. ![]() That's always a good thing, but in this case it was the developer that saved the day. ![]() -- Tim Young Elevate Software www.elevatesoft.com |
