Question about Running rsnapshot
rsnapshot hard-links files that haven't changed to save space. I
am doing two half-day backups and a daily each day. Shouldn't
the inode number as in ls -i filename stay the same for all the
backups? There is a daily.0 file plus a halfday.0 and a
halfday.1 backup and all 3 have different inode numbers for the
same file which hasn't changed since 2008. Doing ls -l on that
file does show 3 links to it. On the working drive, there is
only 1 which is what it should be.
Today, daily.0 represents the full backup of the system
and daily.1 tomorrow will be a renamed version of today's daily.0
directory. df -h looks good in that disk usage appears to be the
equivalent of one full backup even with 3 intervals of backup now
so I am curious as to why the inode numbers for hard links to the
same file are different.
