"Revision 9 is online (135 pages, 3.4 MB)
Revision 9 changes: complements about Timeshift in "Proposed minimum backup and restore strategy", typos, small corrections."
When I was reading that edited portion, it seemed to contradict itself somewhat.
At one point it says timeshift is unreliable and buggy.
"TimeShift is not reliable, and has several annoying bugs:
file "info.json" may be corrupted or missing (this seems to be corrected in "22.11.2" version,
see
https://github.com/linuxmint/timeshift/issues/108),
on Linux Mint 21.x / Ubuntu 22.04, a rsync update breaks TimeShift and prevents it to
work, see
https://github.com/linuxmint/timeshift/issues/152,
it does not back up snaps, see
https://github.com/linuxmint/timeshift/issues/179.
Timeshift issues, 128 open ones when writing this document, can be followed at

Timeshift should not be considered as a system backup tool, since it is not reliable, and it is not
always able to recover a functional system after a crash
(see
viewtopic.php?t=331605).
Moreover, Timeshift use is a security risk: Timeshift reads / writes hundreds of thousands files, in
the operating system. It so offers a large attack surface."
Later on it advises using it and recommends a schedule and how many snaps to keep.
"When your operating system is running, make a Timeshift snapshot.
Periodicity: once a day, or once every two days.
Keep the latest two snapshots."
Does that section of the tutorial need clarifying?
