SuperDuper! at a crawl

[Nick]

I have SD! scheduled to run late every night; my computer is scheduled to sleep several hours later.

Usually, it takes about a half-hour to an hour (depending on what I might be doing at the time) for SD! to complete its Smart Update. When my machine woke up this morning, however, SD! was still running.

I then realized that a while before SD! had began its backup, I had initiated a ClamXav scan, and it also was still running (I had mistakenly told it to scan my entire Home folder!). So, I quit ClamXav, fully expecting SD! to quickly finish its routine. However, it's still moving at a crawl (0.20 MB/s).

Should I expect SD! to return to its normal speed, or do I need to first quit and restart SD!?

Hard to say - I don't know why things are going slowly. What kind of backup drive are you using?

Same one I've always used: Seagate FireWire 800/Icy Dock enclosure (got them last September).

I'd try stopping it and restarting your Mac. Something seems wrong there... shouldn't be running that slowly.

Will tell SD! to Stop, then restart my Mac and restart SD!

I'll get back to you in perhaps 20 minutes.

Well, restarting everything seemed to work. The backup initially proceeded very slowly again; after a while, it picked up speed. It took about a half hour to complete (which is what I'd call "normal").

I'm puzzled what the problem may have been.

Oh well.
