If you want to access the backup drive from foreign operating systems:
If interoperability is a consideration, FAT32 and NTFS should also be
considered. FAT32 is widely used for removable flash media but has a 4GB
file size limit, no journaling, and no support for permissions. NTFS is
widely used for external hard drives and has journaling and support for
attributes. If you buy a consumer-grade external hard drive, it will
most likely be formatted with NTFS. Backup archives (such as tar
archives) can be used to preserve Linux file metadata (permissions and
timestamps) on foreign filesystems.
