I’m trying to upload a bunch of 300-400 MB files using SFTP.
(I’m a sound tech for my church. I record the services, then edit them for CD mastering. I upload the files so the guy with the CD duplicator can download them and make duplicate CDs before the next Sunday. Otherwise, I’d either have to drive a CD over to his place during the week, or we’d have to delay delivering CDs by a week.)
I get very slow throughput, averaging about 30KB/s. The instantaneous numbers are often much higher, but then it shows “stalled” for long periods. About half the transfers fail with a “broken pipe” error after doing a hundred MB or so.
How can I transfer the files in a way that I can resume a broken transfer instead of starting it over?
How can I figure out where the slowdown is between my computer and the host?
Save the Earth. It’s the only planet with chocolate!
