Re: Backup to USB

Mark -

Have you tried using different types of USB drives for the backup, i.e., an external SSD via USB rather than a memory stick ?

During the backup, perhaps during a period of inactivity from IBM i the USB memory stick is going dormant or disconnects and then when the system attempts to write to it again it gets hung while the USB drive is waking up.
I was investigating the use of an external USB disk drive on my Tablo over-the-air DVR and they warned that using certain USB devices could cause failures while recording programs because of this issue.

Does anyone backup their i to USB? What has your experience been?

For a while I was backing up to USB and it was working fine, maybe it took 2 - 3 hours.
A couple of months ago the USB backup seemed to go to sleep for a 3-5 hours in the middle of the backup,
then again further down. It started before I had put on the latest cume and group PTF's.
The situation did not improve after I put the PTF's on.

As a comparative test, a functionally identical backup is being done to tape first
and it completes within a reasonable amount of time (about 2 hours.)
Now, after running 9+ hours I need to cancel it to let production run,
so I don't know if it's just hanging or it's doing something. A guesstimate of the amount being saved is 150 GB.
