I have been successfully deleting files from backups for some time. I use
basic a basic `find <dir> -iname <name> -exec rm {} \;` to hunt down files
and delete them. I have never had any problems recovering the data as the
restore process doesnt have a file list it goes off of but just processes
each file in the directory.
to delete all mp3 files from the pc directories
I like to use regular expressions as it reduces the chance of getting the
wrong files.
find /path/to/backuppc/pc/ -regex './.*\.mp3$ \*.mp3 -exec rm {} \;
be carefull with find and regex as you need the ./ at the front. ./ in this
circumstance is specifically "begins with a directory". then .* which is
anycharacter followed by any number of any characters, \.mp3 is saying use a
real period instead of the any wildcard that . represents followed by mp3,
the $ means the end of the line so you wont match a file like
/path/path/info_on.mp3.files.txt
but would match
/path/path/info_on.mp3
you dont need to do anything with the cpool/pool as the backuppc_nightly
will clean that up. Also, the file names there are mangled beyond
recognition so find would help you anyway.
I use -or and search for video files, mp3 files, temp files
abbr vers:
find /path/to/pc/ -regex './.*\.mp3$' -or -regex './.*\.avi$' -or -regex
'./.*\.mpg$' -or -regex './.*\.mpeg$' -exec rm{} \;
I run it in this way because then find only runs through the filesystem 1
time where running these seperately would run it over and over.
Also, you need to be aware of the filename mangling done so you cannot
search for /myfile.ext but instead must search for /.myfile.ext or
/.*myfile.ext (with regext) or /*myfile.ext if you are using the standard
wildcard *
good luck.
