RE: Backing up Samba share to USB jump drive?

The files to be backed up are Word, Excel, PDF, etc. Every jump drive I've seen comes pre-formatted as FAT-32. The only problem with this is you'll lose POSIX file permissions when you copy the files. Use the tar program on the UNIX system to save your files then copy them over, this will preserve permissions, etc. Ted ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

If you don't want to save multiple versions of the same tree (from different dates), you could use rsync. It might be a lot quicker than cp because it skips files that haven't changed since the last backup.

I assume the drive will have to be mounted like any other drive... Reformatting as UFS seems a good idea. Most drives come with a FAT32 filesystem, which has to use large clusters (16 or 32k) on bigger drives. This can waste a lot of space if you're backing up lots of small files. Have a look at http://en.wikipedia.org/wiki/File_Allocation_Table#FAT32 Additionally, you'll have to recompile the kernel to support FAT32 filesystems 128GB, IIRC.

Backing up Samba share to USB jump drive?
Here's another round of dumb questions for ya: Can USB jump drives be used to back-up a Samba share? If so, what do I need to do to prepare the USB drive to accept files? Since I don't really need to compress or encrypt, I was thinking about simply copying the entire directory tree using the cp command, instead of using dump, tar, cpio. Will this work, and is it a good idea? The filesystem to be backed up is a single common UFS shared via Samba. All PC users have access to the same set of files (no user-specific directories).

You can leave the drive formatted FAT-32 for compat with other OSen, or you can newfs it to a ufs filesystem to maintain unix-style file permissions. In my experience, jump drives behave just like any other drive. -- Bill Moran http://www.potentialtech.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
