NTFS Limits On Linux

I've come unstuck with my backup approach of using an external USB drive on Linux formatted with NTFS.  Duplicati puts lots of files in a single folder for a big backup.  I ran up against the limitations of ntfsmount.  The ever helpful serverfault hive mind told me I should really be using ext3.  I agreed with them.

Here's the steps to try again.
  1. umount /dev/sdb1
  2. Unplug an copy anything important over to a windows PC
  3. Plug back in
  4. mkfs.ext3 /dev/sdb1
  5. mount /dev/sdb1 /mnt/usbdrive

You can increase the size of the volumes that Duplicati stores easily. For a backup to a local drive, a file size of 1GB seems fine.

That's really good advice. I've increased my volume size to 100MB. I'll see how it performs.
