Compare Error Using Copy Function on NAS


Recommended Posts

Hi,

 

I've been using a copy script to backup from a NAS(ext4) to an external HD (HFS format). The operation completed and took nearly 9 hours for about 95,000 files. On verification roughly 80 files show a compare error "different data size".

Is this to be expected when copying between different filesystems?

Would I be better off with a backup script rather than copy, which I only used as I didn't want an incremental backup?

 

Thanks

Hi, thanks for the input. I'm using HFS+ and AFP, also the files don't have resource fork. I think it's quite likely it was something that happened in the background since the file size change was quite small, and the the time between copy and compare was quite long. I have since copied them again using a backup script instead of copy and had no discrepancies.
