Subject: | Hard links on a UDF file system |
I have a removable disc (IOMEGA REV), and I want to use cygwin to take backups using cp -l and rsync as per http://www.mikerubel.org/computers/rsync_snapshots/ This requires hard links to work, which they do on the NTFS partitions, but the IOMEGA has a UDF file system and they don't seem to work there (revealed by ls -i). I believe UDF supports hard links (http://www.k-par.com/pdfs/resources/whitepaper/DVDWhitePaper.pdf), so maybe its just Cygwin that does not allow them? Can anyone help? Some additional background: My first thought was to reformat the IOMEGA to NTFS but I found I could not. IOMEGA's web site says the following: * > *Why does the Iomega REV drive use the UDF file system for PCs?* > The UDF file system is the file system of choice as it overcomes many > of the limitations of other popular file systems. The FAT32 file > system has a 30GB format limit and a 4GB file size limitation. The > NTFS file system does not support removable media. UDF also allows > Iomega REV disks to use advanced ECC error correction on its media. *I am not sure if that claim is true, but I have not been able to find a way to format the disc to NTFS. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
