[Help-tar] Incremental rename of folders

[Kai Stian Olstad]

Hi

I'm trying to use tar incremental to synchronise Ubuntu apt repository 
created by apt-mirror on to a isolated network.

The first thing I did was to rsync the files to a usb and then from usb 
to destination.
Since this two folder now is in sync I ran tar to /dev/null to create 
the snar file.

  tar -c -g /var/lib/tar/snar/ubuntu.snar /data/ubuntu -f /dev/null .

After that apt-mirror was executed followed by the tar like so

  apt-mirror
  tar -c -g /var/lib/tar/snar/ubuntu.snar /data/ubuntu -f 
/data/backup/ubuntu.<seqnr>.tar .


I then tried extracting the tar files on the destination server in the 
correct sequence with

  tar -Gx -f /data/backup/ubuntu.<seqnr>.tar -C /data/ubuntu

The tar's did not contained a lot of changes but the extraction work 
fine.


I then did a massive cleanup(removed old unsupported versions) on the 
source server. apt-mirror do this by creating a clean.sh files the 
removes the old files and folders.
clean.sh does not do anything other than a rm -f on files and rmdir on 
empty folders.
This script removes about 300 GB and several hundred files.

After I ran the tar command as before and the extraction on the 
destination server, but that gave some errors.

  tar -Gx -f /data/backup/ubuntu.8.tar -C /data/ubuntu
  tar: Cannot rename 
‘./no.archive.ubuntu.com/ubuntu/pool/main/c/compiz-fusion-plugins-main’ 
to ‘./no.archive.ubuntu.com/ubuntu/dists/raring-updates/universe/i18n’: 
Directory not empty
  tar: Exiting with failure status due to previous errors
  The tar command failed, aborting.

Tried it ones more:

  tar -Gx -f /data/backup/ubuntu.8.tar -C /data/ubuntu
  tar: Cannot rename 
‘./no.archive.ubuntu.com/ubuntu/pool/main/c/compiz-fusion-plugins-main’ 
to ‘./no.archive.ubuntu.com/ubuntu/dists/raring-updates/universe/i18n’: 
No such file or directory
  tar: Exiting with failure status due to previous errors
  The tar command failed, aborting.

Added a verbose:

  tar -Gvx -f /data/backup/ubuntu.8.tar -C /data/ubuntu
  Extracting /data/backup/ubuntu.8.tar to /data/ubuntu
  ./
  tar: Cannot rename 
‘./no.archive.ubuntu.com/ubuntu/pool/main/c/compiz-fusion-plugins-main’ 
to ‘./no.archive.ubuntu.com/ubuntu/dists/raring-updates/universe/i18n’: 
No such file or directory


I tried to list the content of the tar and I get this
  tar --list --incremental --verbose --verbose -f ubuntu.8.tar | head -n 
64

Source server:
  RedHat 6.6
  tar 1.23

Destination server:
  Ubuntu 14.04
  tar 1.27.1

Does anyone understand why tar tries to rename folders when the clean.sh 
does not do anything more than rm and rmdir?
Any help with this would be appreciated.
