I thought I'd make a new thread after my previous one about possibly using JetBackup so I could get some advice about my actual issue. I'm currently using cPanel's built-in backup configuration, using an S3 destination, and then not retaining the backups in the default backup directory after they're uploaded. The backup type is compressed. My server is getting closer and closer to running out of disk space every time it creates the backup. If I don't address this soon, it will no longer be able to back up. (This is about space on the server itself, not the backup destination.) Once it moves the backup to the remote destination, everything is back to normal since I'm not retaining the backups locally. What are some ways I can reduce the amount of space the server uses while it creates the backup? Do uncompressed and incremental also need to use all of this space, or is this specifically related to using the compressed method? My current idea is to replace my Amazon S3 remote destination with some other host that supports rsync so I can use incremental, but I'm not sure exactly how these other methods work. Do they still need to be copied to the backup directory before uploading remotely or can they be uploaded directly from their source? About half of the data I'm backing up is from databases. I realize these would take up extra space either way since they need to be dumped, but I'm hoping at least regular files don't need to be copied to the backup directory before uploading.
