Re: [gentoo-user] Good file system that recovers from a power failure.

[Arthur Britto]

Hi,

If you don't use a UPS, what you want is journaling file system that is
configured to do a lot of syncing.  However, the syncing will make
writing really slow.

Ext4 has the latest features.  Especially, if you want to use an SSD.

To really be reliable you must use a UPS which can signal when a clean
shutdown is needed.  Not having one is just asking for grief.  With this
functionality, you will not need the excessive syncing and writing can
be fast.

Additionally, if you don't have the cleanest power, having a UPS will
extend the life of the hard drive and potentially the rest of the system
as well as eliminating apparently random data corruption.

I very much like the CyberPower Intelligent LCD Series.  It has a USB
connection which works with sys-power/nut and an LCD display.
