A question you can discuss forever :-) or just ignore... Personally, I typically use ext2 or FAT32, depending on needs. Journaling is - often - not very useful here, as it slows down throughput even more, and as long as you don't journal the actual data doesn't help you much in case of failure - I don't only need filesystem integrity for backups, I need to be sure of the actual file data. Thus, IMO, un-journaled file systems are ok for backup purposes. > Is there one that maximizes > available space? Can I just give bacula the whole partition /dev/sdg1 > unformatted? Bacula needs a file system to work on. You could save partitioning, though (use /dev/sdg as a whole) but Iw ouldn't recommend that as it confuses others who need to access that disk. You can tweak the ext2/3 filesystems to create a minimal number of inodes, which is ok if you expect to store only large files. That saves a bit of the capacity. You can also set the reserved blocks to 0. If you need to be able to use the backups on windows machines, FAT32 is the most reasonable FS, unless you trust the linux NTFS drivers. None of these FSes can be tweaked for maximum net capacity as far as I know. Short answer: Use whatever you're comfortable with, and keep in mind that journaling can negatively affect performance and might not gain you any data security.
