I have an application that will, more often than not, have to run unattended overnight. It generates checksums and creates a digital package format of arbitrary data sets, per the Library of Congress Bagit specification. Yesterday I ran the first large scale test, on 908 files, roughly 1.5TB of data - most of these are quicktime files or WAV files, so the checksums take quite some time.
This morning I came in and saw that it was almost exactly where I would have expected it to be when my screen went to sleep about an hour after I left. To be clear, the *computer* is not asleep, just the screen. Hard drives are set so they never spin down.
Moments after I arrived and saw that it had barely budged from last night, it started running again, suggesting that the application was suspended all night.
How can I prevent this? Other applications, such as DropBox, remain working all the time. I regularly set up DropBox uploads that go for 5-6 hours before going home at night. Same with Chrome - We often have to upload files to Amazon Prime Video that take 10+ hours, so we do that overnight, and it's never been an issue.
