\fB\-session_log\fR path
If path is not empty it gives the address of a plain text file where
a log record gets appended after each session. This log can be used to
determine the start_lba of a session for mount option sbsector= from
date or volume id. With non-multi-session media this is currently the only
way to obtain this parameter.
.br
Record format is: timestamp start_lba size volume-id

The first three items are single words, the rest of the line is the volume id.

on media and if the expected changes are much smaller than the full backup.
An update run will probably save no time but last longer than a full backup.
.br
With overwriteable media like DVD+RW or disk files, the older backup versions
cannot be retrieved. But with multi-session media and mount option "sbsector="
it is possible to access the session trees which represent the older backup
versions. sbsector of a session is its "data lba:" number from xorriso
option -toc.
With \fBmount\fR option \fB"sbsector="\fR it is possible to access the session
trees which represent the older backup versions. Multi-session media can tell
the sbsector by xorriso option -toc, as "data lba:". For other media one
may set before writing a suitable path for xorriso option -session_log where
the sbsector number gets recorded as the second word in each line.
.br
With CD media, Linux mount accepts session numbers directly by its option
"session=".
