Seagate is working with Dantz on a Mac OS X version of Retrospect. The TapeStor Travan works only with Mac OS 9. In other words, you only copy the files that have changed, so your evening backup might take only a few minutes. However, after the initial backup, Retrospect allows you to perform incremental back ups. It takes about ten hours to back up 20GB of data. If you seem to fill up disk space the same way Barbie eats up closet space, be wary of the TapeStor Travan. You’ll still be able to use your computer, but images will render slowly and video will stutter. ago Well maybe do weekly backups and remove said tape (s) when done, assuming the weekly backup would complete in a timely manner. (Image and audio files are often compressed already, so those files won’t benefit from compression.) The trade-off, however, is the burden on your CPU. Tape tape library will be online 24/7 for incremental backup. We were able to shave 15 percent off of our backup time by turning on software compression. For this reason, compressing the data in the computer before you copy it to the tape is the best solution, since it cuts down on the amount of data you’ll have to transfer.
Although hardware compression is generally faster than software compression, in this case it doesn’t matter: the bottleneck is simply moving over to the USB connection. The TapeStor Travan doesn’t offer hardware compression. That’s fine for a keyboard or mouse, but it can be a problem if you need to move large files. USB’s maximum data rate is 1.5MB per second. Strangely, Retrospect recognizes the TapeStor Travan as a SCSI drive instead of a USB drive, but this didn’t interfere with operation.

Retrospect is relatively easy to use and includes an adequate PDF user’s manual. The TapeStor Travan ships with Retrospect Desktop Backup 4.3, the standard in backup software. Tape drives don’t show up on your desktop, so you can only read or write to them using software. Although Travan is an older and lower capacity technology, it’s affordable, and its cartridges are widely available. However, if you don’t have dozens of gigabytes of data and USB is your only connection option, the TapeStor Travan is worth considering. With its sluggish connection, Seagate’s TapeStor Travan Portable USB 20 pushes the limit. While this makes perfect sense, there’s a point where a drive is so slow even all night isn’t enough time to complete a backup.
If you use the drive for desktop backup, you can simply start the process when you leave for the day, and by the time you arrive at work the next morning the backup is complete. Some people may tell you that speed doesn’t matter when it comes to tape drives.
