Error reading from backup file mysql
HI:
Stupidly I I entered the wrong delete command and managed to lose 97% of 2million records.
Cleverly I had a backup.
Not so cleverly I get a message 'error reading from backup file' 'unknown object in backup file'
However I have managed to backup AND restore the db since then. The difference is that the offending table was > 1GB (it still reads that even though now tiny).
Does this mean that my old backups are corrupt? I have read that there is 1Gb limit so should I run the script mysql -u<user> -p<password> < <backupfile> .. and do I have to drop ALL the existing tables first (the other 17 tables in the db are fine)?
Finally - a question: I had kept all the data now lost in a dbf file.. IS it easier to reimport rather than restore? And if so how will I know future backups are OK?
Thanks!

Change of plan. I am working on the premise that the restore is failing because the table size has gone over 1gb. I should really reduce the table size (I can do some normalisation) but instead am willing to buy navicat to use instead of mysqladmin.
Does anybody have experience of using navicat; specifically restoring tables over 1gb?
And I do like the idea of navicat allowing import of dbf....
Thanks!
