Subsequent runs would put links of newly BackupPC_dump'ed files into the pool. The copied files would be duplicates of the pool files, but would not be linked. As the copied backups are expired wasted space will be recovered. > > You might have to run BackupPC_link afterwards - it should integrate the > files into the pool... but I'm not sure. > In order for this to have any effect, you'd have to recreate the "$datadir/$pc/NewFileList.$backupNumber" file which tells BackupPC_link which files need to be linked. Basically, in the case above, you'd need to traverse each copied $datadir/$pc/$backupNumber/ directory and for every file found write out... $poolHashFileName $fileSize $fileName ...to "$datadir/$pc/NewFileList.$backupNumber". So if you copied in 10 old backups, you'd have to traverse 10 directories and write out 10 NewFileList files. Unless you are short on disk space or are planning on keeping the relocated backups around forever, that is likely more trouble than it's worth. > Tino. > Chris ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
