What's the right filesystem for your portable backup drive?

Wed, 16 Apr 2008 18:00:00 GMT
So you just bought an external hard drive for backups. Now, with what filesystem should you format it? Ext2? FAT32? No matter which one you choose, there are trade-offs to consider.

FSTYP(8)						    BSD System Manager's Manual 						  FSTYP(8)

NAME
fstyp -- determine filesystem type SYNOPSIS
fstyp [-l] [-s] special DESCRIPTION
The fstyp utility is used to determine the filesystem type on a given device. It can recognize ISO-9660, Ext2, FAT, NTFS, and UFS filesys- tems. The filesystem name is printed to the standard output as, respectively, cd9660, ext2fs, msdosfs, ntfs, or ufs. Because fstyp is built specifically to detect filesystem types, it differs from file(1) in several ways. The output is machine-parsable, filesystem labels are supported, the utility runs sandboxed using capsicum(4), and does not try to recognize any file format other than filesystems. These options are available: -l In addition to filesystem type, print filesystem label if available. -s Ignore file type. By default, fstyp only works on regular files and disk-like device nodes. Trying to read other file types might have unexpected consequences or hang indefinitely. EXIT STATUS
The fstyp utility exits 0 on success, and >0 if an error occurs or the filesystem type is not recognized. SEE ALSO
file(1), capsicum(4), glabel(8), mount(8) HISTORY
The fstyp command appeared in FreeBSD 11.0. AUTHORS
The fstyp utility was developed by Edward Tomasz Napierala <trasz@FreeBSD.org> under sponsorship from the FreeBSD Foundation. BSD
