Trouble to restore my backup database

[looneytv]

I'm having trouble restoring my old database backup. The Movies.pvd.bak file is pretty big, 900Mb. When I try to restore from the programe it looks frozen for a long time. Maybe I should beprogram waiting for longer...

I have also tried to replace the default MOVIES.PVD file with my Movies.pvd.bak file in the directory -changing it's name to MOVIES.PVD- but when I lunch the programe I get this error:
Specifiel file is not a Personal Video Database XML file.

What's the best way to get my old database back? Thank you so much.

The backup file cannot be restored by renaming it. It must be uncompressed using the restore command in the program. Try waiting longer. If that doesn't work...

I'm not sure it matters, but I would make sure the program is not creating new database with the same name (since it is the default)—that might conflict with the restoration of the old one. Create a new database with a different name, delete movies.pvd (if there is one), and then try restoring.

Thank you SO much Rick. I got my database back. Phew! It was my fault after all forbeing impatient while the database was taking so long to get uploaded so when I click again on the programe it would give me a Windows error. I should just have leave it working on the first place. Learned lesson

You're welcome. You might prefer to make backups simply by making a copy in Windows Explorer and/or including the file in some automated backup routine. It's faster, and you don't have to worry about whether the program will be able to complete the restore function.

I happened to try out Cobian Backup today. It seems very good, and it's freeware.
