Backing up long filenames/paths

Posted on 2011-02-12

We have approx 400GB of data, most of which is cad drawings however when we do a  backup, some of the files/folders won't backup because the filenames/paths are too long.  Is there any way of getting around this without having to change the folder structure or rename files?
We don't want to change the folder structure, firstly because it is time consuming and the staff are used to the current file structure and secondly because some of the cad drawings have xrefs in them which point to other files that may no longer work if the structure is changed.

Use a proper backup software that supports long file paths?
Apart from that, you can use robocopy's.
Some hints:
- robocopy will *by* *default* only copy files that aren't in the target already.
- you can use /mir to delete files in the target that aren't in the source anymore.
- You might want to set /r (retry) and /w (wait) to something more useful in a LAN, like /r:2 /w:1.
- use /copyall to copy NTFS permissions as well.
- Check robocopy.doc in the ResKit installation folder (to run it, you actually only need robocopy.exe), it's a very useful documentation.
- You can safely use /nfl (no file list) and /ndl (no directory list) to reduce the log file size; errors will still be logged.
- Use /np if you're logging to a text file, otherwise the log will be filled with control characters.
- If you're migrating to W2k8, robocopy's already included.

i agree with oBdA, use Robocopy to re-create the file structure.  It keeps the file permissions when copied over to the new directory.

Thanks for the advice, I will give robocopy a go.  
We are also planning on purchasing backup software for daily tape backups including the exchange store, we were thinking of Symantec Backup Exec with the deduplication component as there are lots of emails that contain the same attachment? Would this be the best product or are there better products out there?

Symantec Backup Exec certainly has been on the market for quite some time (used to be Veritas Backup Exec) and should work just fine.
Can't give you any specific advice, they all have their strengths and weaknesses, so "better" is always in the eyes of the beholder.

Do you want to stick with tape?  If not, you might want to consider using a Barracuda.  Nice piece about the Barracuda is there is an offsite backup option for a disaster.  One of the major disadvantages is this solution is not an image based backup.

robocpoy is not a backup software, so it can't do incremental backups; it can only mirror a directory tree. If you want keep a history when using robocopy, you need to copy into as many different target folders (or a set of different external USB drives) as you want to be able to go back.

For mirroring, just include the /mir switch.
Just be aware that if a user deletes a file today, then the mirroring runs the same day in the evening, and the user decides tomorrow that he needs the file back, the mirroring will have done its job and deleted the file on the target as well.
