We have been using ext3 for Linux server off-site backups. With everything else on CentOS 6 being ext4, I'm wondering if it would be a better idea to also have the off-site backups in ext4 too? The off-site backups are often LaCie rugged drives.
I was concerned that in the event of an emergency that an off-site backup has to be obtained quickly, the available servers might be older and not support ext4?
Just wondering if there is a concern about keeping the backups in ext4. Thanks!
