Error -50 on backup to network drive - mlarnes

WOW! Support replied within a matter of hours.
No definite answer, but they tell me that -50 is a timeout error waiting on the network drive.

I find it a bit hard to believe when I can edit iMovie digital video using the same drive, but I shall see if it is trying to access the network at the same time as autoupdate or similar tasks, maybe try it in the middle of the day while supervised too.

Will post back results. At the end of the day, maybe it is expecting a bit much to be running backups to a PC drive across a network using a freeware utility, but bonus if it does work!

Error -50 on backup to network drive - Special K

I have the same problem. Review the Silverkeeper log and find the last file and put it on the exclusion list. That's how I get past it. It's a bit of a pain to have deal with it that way but it works and is FREE.

Error -50 on backup to network drive - Mike - LaCie

Mike from SilverKeeper here...

the error -50 results at the end of the backup when the network drive fails to respond within a reasonable time.

Why at the end? This is when SilverKeeper moves the temporary backup files copied and merges them into the previous backup. All this file renaming and moving can be slow on some network shares. Error -50 can also occur in the middle of the backup, if there are thousands of files within a folder that need updating.

Further, we try to set the creation/modification dates to match the originals, and have to do that on a file by file basis after the copying is done.

The challenge for us - how to determine a reasonable time to wait.

A workaround is to treat every backup as a fresh new backup, rather than trying to update an existing backup.

Mike

Error -50 on backup to network drive - mlarnes

Thanks Mike, and thanks for your prompt and precise assitance!

One solution that has solved pretty much all the problems is to back up to an image file.

So - I created a 40GB image file which is sat on my PC based network drive.

After mounting the image, I set this as the destination.

Advantages - This is now a Mac drive despite it's PC based location. All permission information is retained in the backup! (Permission information is turned off by default for images, by SilverKeeper prompts and turns it on for you). Also, no more Error -50's.

Disadvantages - I have to make sure the image is mounted every time the backup is scheduled. I figure it will not be bootable in any way either, but that was never an objective for me anyway.

Notes - When first trying to create the image, Disk Utility told me the max size for an image on the drive (NTFS network drive) was only a few hundred MB. When I next tried, I set the size before setting the location, and it let me then create the full size image. It seems to be working fine so far, so I hope this isn't going to catch up with me in some way!

I am more than glad to recommend SilverKeeper and Lacie for this most generous and unusually well supported Freeware offering.
