[ADMIN] backup problem

[Rodrigo Sakai]

Hi, I'm trying to do a backup of a database that is larger then 4 GB. But it gets an error when the file size gets 1.2 GB! I think its an Operational System problem (linux)! So, I want to know if exists some solution to backup my database??     The command that I used was=     pg_dump -U postgres -d dbdeveloper -a -v -D -f 'backup.sql'     The operational system is linux with etx filesystem, and the version of postgres is 7.4!!     Thanks in advance!
