Backup Central

hello everyone,
i'm using rsnapshot for sometime now.
i did an rsnapshot du and  got curious to see if there is a way to see what files have been changed between backups.....

the reason is that i see a somewhat large chunk of data being changed from day to day and it might not be reasonable:

root < at > samothraki:~# rsnapshot du
1.8T    /mnt/hd/snaps/dly.0/
24G     /mnt/hd/snaps/dly.1/
24G     /mnt/hd/snaps/dly.2/
26G     /mnt/hd/snaps/dly.3/
390M    /mnt/hd/snaps/dly.4/
390M    /mnt/hd/snaps/dly.5/
1.1G    /mnt/hd/snaps/dly.6/
12G     /mnt/hd/snaps/dly.7/

these are daily backups of the last week.. since the office was closed this week it feels like a few TOO MANY files have been altered (say between dly.3 and dly.4), and i wonder what has indeed been changed....

so is there a way to check which nodes have been altered?
or a script perhaps?

thank you for your help

You might be able to use rsync with --dry-run to show the changes.
Something like 'rsync -a --dry-run dly.0/ dly.1/' to show the things
in dly.0 which would have to be transferred to dly.1. Be very
careful, though .

--dry-run tells rsync to not actually make changes. If you
accidentally omit it, you'll overwrite dly.1/ with dly.0/ .

Hallo, Athanasios,

Du meintest am 30.12.11:

so is there a way to check which nodes have been altered?
or a script perhaps?

rsnapshot help

leads to

rsnapshot diff

or (p.e.)

rsnapshot diff daily.3 daily.4

Viele Gruesse!
Helmut

As useful as this can be in the small case, it's deadly in the case of
symlink recursion, where something like /usr/include/foo/bar is a
symlink to "..". This is an old behavior common in making include
structures accessible with different layouts for different software
packages, and diff can wind up recursing its way right down the
symlinks forever and ever and ever until it reaches the maximum
filename length or number of symlinks supported by the kernel.

Been there, done that, have the T-shirt.
