Restoring files from backup based on ctime
Hello, I need to restore some yesterday emails from backup within a 5 hours timeframe

this is a openvz container, backup is made by rsync files to another partition in the same server

I have tried to do this

Code:
#!/bin/sh

cd /vz/backup/414/home/smartftp/mail/domain1.com/
for dir in new cur
do
    for dir2 in $(find /vz/backup/414/home/smartftp/mail/domain1.com/*/$dir -type d )
    do

// Replace the folder name
dir3 =$({$dir2/backup/private})
find $dir2 -type f -mmin -840 -mmin +540 -name "*host.*" -exec rsync -av $dir2 $dir3 \;
    done
done

But I am stuck trying to replace the folder name to rsync the files to the working dir from backup to private

Please advice

I guess there is something about the actual dir structure that keeps this from infinite recursion? New has a dir new under it and cur has a dir cur under it? I get lost quick. How does the find exec act on the file found, no {}?

The problem here is not the recursion that works on the backup side only, neither creation of folders as find is only searching for files in the two folders new and cur.

The problem is how to modify the folder path rsync parameter from "backup" to "private"

i guess it is just matter of good shell variables handling but I am not an expert on this, so I just have the logic but not the actual command to turn this parameter from

/vz/backup/other/folders

to

/vz/private/other/folders

i tried parameter expansion but it fails

dir3 =$({$dir2/backup/private})

Well, rsync is just scp/rcp on steroids, so you can do it yourself file by file or -r tree by tree.

Well, scp would do the job, but still do not solve the main question.

How do I replace this location on the variable from backup/ to private/ ?

Any suggestions ?

try something like this in your code.

Code:
 echo ${dir2/backup/private}
/vz/private/414/home/smartftp/mail/domain1.com/

I have the impression you can simplify your script. DGPickett already mentioned it: the files are copied multiple times.
If you have GNU find then the following could work:
Code:
#!/bin/bash
srcdir=/vz/backup/414/home/smartftp/mail/domain1.com
dstdir=/vz/private/414/home/smartftp/mail/domain1.com
cd $srcdir || exit # fatal
find */{cur,new} -type f -mmin -840 -mmin +540 -name "*host.*" -print0 |
 xargs -0 rsync -av $dstdir

For testing, have rsync --dryrun -av ....
