Dear all,

Running BackupPC V4.4.0-3 on Debian 11 (Bullseye) and having some unexpected 
messages from
BackupPC_migrateV3toV4 also if BackupPC_migrateV3toV4 -m don't report any 
issues at the beginning:

1) unexpected progress reported:
   BackupPC_migrateV3toV4: migrating host fileserver backup #5115 to V4 (approx 
31 files)
   fileserver #5115: 45.2%
   fileserver #5115: 71.0%
   fileserver #5115: 1003.2%
   :
   fileserver #5115: 932422.6%
   fileserver #5115: 932429.0%
   BackupPC_migrateV3toV4: converted backup in 
/var/lib/backuppc/pc/fileserver/5115; removing 
/var/lib/backuppc/pc/fileserver/5115.old
   BackupPC_migrateV3toV4: migrating host fileserver backup #5116 to V4 (approx 
516 files)
Directory 5115 looks good, Having attrib_<md5> file as well as all expected 
directories. Also if
fileserver #5115 reports an unexpected progress the 5115.old has been removed. 
Can I expect that
backup #5115 is successfull migrated?

2) Progress not going till 100%
   BackupPC_migrateV3toV4: migrating host gerhardpc1 backup #0 to V4 (approx 
254099 files)
   gerhardpc1 #0: 0.0%
   BackupPC_migrateV3toV4: can't read attribute file ./fC/fProgramme/attrib
   Unexpected magic number 0x78da5550 read from ./fC/fProgramme/attrib
   BackupPC_migrateV3toV4: migrating host gerhardpc1 backup #0 to V4 (approx 
254099 files)
   BackupPC_migrateV3toV4: can't read attribute file ./fC/fProgramme/fAlwil 
Software/attrib
   Unexpected magic number 0xd7da130f read from ./fC/fProgramme/fAlwil 
Software/attrib
   :
   gerhardpc1 #0: 0.6%
   :
   gerhardpc1 #0: 7.2%
   BackupPC_migrateV3toV4: converted backup in 
/var/lib/backuppc/pc/gerhardpc1/0; removing 
/var/lib/backuppc/pc/gerhardpc1/0.old
   BackupPC_migrateV3toV4: migrating host gerhardpc1 backup #145 to V4 (approx 
72412 files)
Directory 0 looks good, Having attrib_<md5> file as well as all expected 
directories. Also if there
are this error messages and progress isn't going till 100%, 0.old has been 
removed. Can I expect
that backup #0 is successfull migrated?

3) migration left the 145.old directory
   BackupPC_migrateV3toV4: migrating host gerhardpc1 backup #145 to V4 (approx 
72412 files)
   gerhardpc1 #145: 0.0%
   :
   gerhardpc1 #145: 17.0%
   BackupPC_migrateV3toV4: can't read attribute file ./fC/fProgramme/attrib
   Unexpected magic number 0x78da7d55 read from ./fC/fProgramme/attrib
   :
   gerhardpc1 #145: 21.6%
   BackupPC_migrateV3toV4: converted backup in 
/var/lib/backuppc/pc/gerhardpc1/145; removing 
/var/lib/backuppc/pc/gerhardpc1/145.old
   BackupPC_migrateV3toV4: migrating host gerhardpc1 backup #146 to V4 (approx 
72407 files)
Directory 145 looks good, Having attrib_<md5> file as well as all expected 
directories.
sudo -u backuppc /usr/share/backuppc/bin/BackupPC_attribPrint 
/var/lib/backuppc/pc/gerhardpc1/145/fC/fProgramme/attrib
as well as 
sudo -u backuppc /usr/share/backuppc/bin/BackupPC_attribPrint 
/var/lib/backuppc/pc/gerhardpc1/145.old/fC/fProgramme/attrib
list the attributes.
Also if I got this errors , the attrib files are differents and 145.old is 
still available, have I
lost this backup or can I still repair the issues?

4) 
   BackupPC_migrateV3toV4: migrating host gerhardpc1 backup #146 to V4 (approx 
72407 files)
   BackupPC_migrateV3toV4: can't create 
/var/lib/backuppc/pc/gerhardpc1/146.v4/refCnt/needFsck.mig (0)
   BackupPC_migrateV3toV4: can't create 
/var/lib/backuppc/pc/gerhardpc1/146.v4/refCnt/noPoolCntOk (0)
   BackupPC_migrateV3toV4: can't read attribute file ./attrib
   bpc_attrib_dirRead: can't open ./attrib
   gerhardpc1 #146: 0.0%
   BackupPC_migrateV3toV4: converted backup in 
/var/lib/backuppc/pc/gerhardpc1/146; removing 
/var/lib/backuppc/pc/gerhardpc1/146.old
   BackupPC_migrateV3toV4: migrating host gerhardpc1 backup #154 to V4 (approx 
454550 files)

   
The ./gerhardpc1/146/refCnt/noPoolCntOk has been created but is empty. 
backupInfo looks the same as
in 146.old, but reordered. No other files or directories are in 146 and 146.old 
is still available.
Have I lost this backup or can I still repair the issues?

Thanks in advance
Matthias
