Delayed Write Failed backing up to a Seagate PushButton eSATA drive.

It’s not Seagate’s fault.

Originally, I suspected the fixed 5-minute idle shutdown of the otherwise marvelous device would be causing the backup to break and generate annoying application popups and event log entries.

But it ain’t so.

Apparently, thou shall not compress large files on fragmented disks. This in particular true for full backups to external hard drives.

Thanks to "jim".

In my case, the full backups consume roughly 25GB. I do not have problems with the incremental backups because they (no surprise) are usually much smaller.

So the solution should be defragment, then backup. If failed, rinse, disable compression and backup again.

Now, three questions remain:

  1. Why don’t they fix this?
  2. Why, o, why, don’t they have compression in the backup in the first place?  – To help sell tape backup devices?
  3. And, shouldn’t I be using a "real" backup solution?

Backup programs seem to be all crap one way or the other, so I’m rather not spending money.

    Don’t be to angry about commercial backup software. There are a lot of products out there, which saved a lot of people a lot of money in the past. Of course, the better ones are not inexpensive, and have bugs, too.I can only tell about our experience with Acronis TrueImage, where I did a lot of full backups as a desaster recovery scenario I never faced problems, like you describe them.BUT the more the software companies rely on OS features (and I think many of them do use the Micorosoft features for accessing and backing up files that are currently in use), the more likely it will become, that many of these products show the same problems…Nevertheless, if one looks at the number of crashed harddisks (especially the 2.5" disks), I get the feeling, that these diveses crash more often than several years ago. So a full backup, especially of laptops, should be a must. And I mean a full backup for the desaster recovery scenario. I just saw a collegue of mine reinstalling all necessary software on a new harddisk. It took him days to get back to speed after his harddisk crashed.
