In my neuroses, I ran a perl script that recursed through the cpool and checked whether the md5sum of each stored file corresponded to its location in the pool (note when I say md5sum I mean the special notion of md5sum defined in BackupPC::Lib.pm)
1. Out of a total of 855,584 pool entries, I found a total of 35 errors. 2. Interestingly, all 35 of these errors corresponded to 'attrib' files. 3. Perhaps even more interestingly, all but two of the attrib files were at the top level -- i.e., $TopDir/pc/<machine>/<nnn>/attrib (this represents 33 out of a total of 87 backups) 4. None of the attrib files appear corrupted when I examine them using BackupPC_attribPrint So what could possibly be causing the md5sum to be wrong just on a small subset of my pool files? Why are these errors exclusively limited to attrib files of which almost all are top-level attrib files (even though they constitute a tiny fraction of total attrib files)? - Disk corruption or hardware errors seem unlikely due to the specific nature of these errors and the fact that the file data itself seems intact Of course, I could easily write a routine to "fix" these errors, but I just don't understand what is wrong here. I suppose the errors aren't particularly dangerous in that the only potential issue they could cause would be some missed opportunities for pool de-duplication of stored attrib files. But there shouldn't be wrong pool md5sums... ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ 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/
