I use USB flash drives and 480 GB SanDisk portable drives for some backups. I started by using ext4 on one of the flash drives. The next day I tried to boot the computer, but found that the computer hung. Only at this point did I find out that those drives are not capable of journalling.
I use USB flash drives with ext4 for backups and have not had any problems with journalling. I have had at least one successful journal recovery, after an inadvertent disconnection before unmount. What problems did you encounter?
I optimised my ext4 backup filesystems for a small number of large files (compressed archives) with:
mkfs.ext4 -J size=4 -m 0 -T largefile4 -O "^resize_inode" /dev/sdb1 tune2fs -c 0 -i 0 -L Backup /dev/sdb1 My /etc/fstab contains: LABEL=Backup /media/backup ext4 noatime,noauto,user,errors=remount-ro 0 0 Kind regards, -- Ben Caradoc-Davies <b...@transient.nz> Director Transient Software Limited <http://transient.nz/> New Zealand
