How to take snapshot of the filesystem in linux (files, their sizes only, not their data)

We need to take a snapshot of your linux server. We don't want to backup the data, just a snapshot we can compare against changes.

From serverfault gAMBOOKa

• i would recommend checking for md5 sums of files, and not just file size. however:

  find / -printf "%h/%f %s\n" > /some/path/filesize would generate a list of files and their sizes.

  you could also do find / | xargs md5sum 2> /dev/null 1> /some/path/file-md5s to generate a list of filenames and their md5 sums.

  From cpbills

• use

  du <filesystem mount point>
  

  it should give you size and file in full location

  From A.Rashad

• find / -ls > fileinfo.txt
  

  But take a look at tripwire and aide, since that seems to be what you are aiming for anyway. Also note that rpm can check files against checksums and for debian based distributions there is debsums.

  Pier : Agree. Probably tripwire and aide are what he looks for
