We have 18 GB files on server for our website. I tried to take backups using cpanel backup wizards. Since, the files are growing, cpanel backup wizard is now creating corrupted zip files. So I found from Google that Filezilla would be best for transferring large files. But, when download was finished, I could not find some directories. I remember that I queued all files from root (CTRL+A) and started processing. One big zip failed, and I requeued that again.
What could be the problem for us? What are the other solutions we could follow? Cpanel backups are creating corrupted backups. Our download speed (500Kb to 1.5Mb). It would be good to know why we have corrupted backups and why we are failed and what are the other good solutions. I'm not even sure that I should contact hosting.
We are using a shared linux hosting.
