i get the same error. my database size is above 1 GB. Attachments size is way beyond. What I have figured is that this happens when your db and attachments are too big to handle. Basically it creates the catsbackup.sql and catsbackup.sql.n files but cant make zip utility combine attachments
still trying to upgrade from 0.7.1 to 0.9.1 but no success. and there is no command line backup in 0.7.1
When i try to create a catsbackup.back file on my own (catsbackup.sql becomes database, catsbackup.sql.n files go into db folder and attachments remains as is), I get the following error:
Query Error -- Please Report This Bug!
MySQL Query Failed: Table 'cats09.attachment' doesn't exist
