I have been saving my backups to an XFS partition on an external Seagate
drive. I tried to do it with Ext4, but had too many failures.
For the past month or so, we have been experiencing very severe storms,
some with lightning. After the last one, my external disk became
inaccessible. Looking around the Web, I find that this was a regular
occurrence with CentOS 7, whose default filesystem was XFS. Usually,
running xfs_repair is all that is needed, but this time, no primary or
secondary superblocks can be found, and xfs_repair gives up. The
computer does not now recognize the device.
Are there any other steps I can take? btrfs is suggested as ideal for
backups, but it is largely incompatible with any other filesystem, and
it is said to be overkill for a single workstation. In any case, that
is a question that arises only if I have to buy a new drive.
