Obviously backups are essential, especially if you are still learning
and like me sometimes do something that results in rather catastrophic
states. Also, I do not keep anything in any cloud. It only exists on
my Qubes install. So again: backups are essential.
There are efforts of providing incremental backups for Qubes to only
copy what changes and reduce backup time. I have no experience with that
.
Here is what I do: with the build-in backup of Qubes a full compressed
and encrypted backup of everything on my machine takes between 4-5
hours and consumes ~260 GB.
I have a 2TB USB3 external drive that is encrypted. When I am ready to
go to bed, I shutdown all Qubes except sys-net (which in my case
doubles as sys-usb), delete the oldest backup on the drive and start
the backup with the option to turn the computer off once it is done.
This way I always have the last 7 days. I also have a second drive
where I manually copy the last backup of the month for the last 4
months. However, if I do something stupid I usually am aware of it
right away and simply restore the backup from last night.
Another advantage is that you can usually very well recall what you
have been doing since the morning and copy just those few mails,
projects / documents to a USB stick to be restored after restoring the
big backup.
Side note: maybe I do something fundamentally wrong, but my SSD based
system slows down noticeably after several months. There's nothing
like a clean Qubes install and restoring from backup to regain full
performance. ;-)
Also often I mess up just a single template, which can be restored
much faster. In general, besides all the security related advantages
of Qubes, I find it greatly liberating to have the freedom to
experiment knowing I can always switch back to the working template /
backup. Or even move my entire install to another computer as long as
that computer runs Qubes.
Fully recovering from any disaster never takes more than 5 hours. Try
doing that with any other OS!
