Under certain circumstances a dedicated server or VPS can run into problems when trying to access a backup file.
Behind the scenes the Site Backup and Recovery Tool has attempted to access a particular backup file. In many cases the issue boils down to the tool not coping with a compressed backup file that's larger than 2GB.
The below solution overcomes the compressed file stuck issue which is preventing you from opening a backup on your dedicated server or VPS.
After completing the above steps your backups will be performed incrementally and without compression. While it may mean a bit more disk usage, it'll also mean your backup and recovery software can work without getting bogged down on large compressed files.
