Hi,
since nobody cared on backuppc-users maybe -devel is the right place.
i'm running BackupPC to backup the local machine and might
have discovered a bug regarding wrong owner/permissions of
directories/files created by BackupPC_dump.
uid(myuser) = 1000
gid(myuser) = 1000
uid(backuppc) = 1003
gid(backuppc) = 1003
Owner/permissions in filesystem:
# ls -lnd / /home{,/myuser,/myuser/.maildir,/myuser/.maildir/.folder}
drwxr-xr-x 19 0 0 4096 May 27 19:58 /
drwxr-xr-x 5 0 0 4096 May 27 19:13 /home
drwx------ 31 1000 1000 4096 May 27 19:56 /home/myuser
drwx------ 59 1000 1000 4096 Apr 26 19:27 /home/myuser/.maildir
drwx------ 6 1000 1000 4096 Jan 13 2005 /home/myuser/.maildir/.folder
Owner/permissions in backup after
# BackupPC_dump -f myhost (created Backup #45)
# BackupPC_tarCreate -h myhost -n 45 -s / -L / | head
40755 1003/1003 0 ./
40755 1003/1003 0 ./home/
40755 1003/1003 0 ./home/myuser/
700 1000/1000 0 ./home/myuser/.maildir/
700 1000/1000 0 ./home/myuser/.maildir/.folder/
As you can see, the permissions and user/group are wrong for the
first 3 entities.
As a result when restoring /home/myuser/.maildir to /home this afternoon
backuppc changed owner and permission on /home to the wrong values
(why did it touch /home in the first place?).
# egrep -v '(^#|^$)' /etc/backuppc/pc/myhost.pl
$Conf{XferMethod} = 'tar';
$Conf{TarClientCmd} = '/usr/bin/sudo /usr/local/bin/tarCreate -v -f - -C
$shareName --totals';
$Conf{TarClientRestoreCmd} = '/usr/bin/sudo /usr/local/bin/tarExtract -p
--numeric-owner --same-owner -v -f - -C $shareName';
$Conf{TarIncrArgs} = '--newer=$incrDate $fileList';
$Conf{TarFullArgs} = '$fileList';
$Conf{BackupFilesOnly} = ['/home/myuser/.maildir'];
$Conf{BackupFilesExclude} = undef;
$Conf{ClientNameAlias} = 'localhost';
# cat /usr/local/bin/tarCreate (tarExtract according)
#!/bin/sh -f
export LC_ALL=C
exec /bin/tar -c "$@"
BackupPC 3.1.0
GNU tar 1.19
Sudo 1.6.8p12
One more thing:
1. Browsing the backups via http interface and listing the contents
of /home/myuser
2. Selecting the checkbox left to ".maildir" and click button
"restore selection" (don't know the english version, using german one)
3. On next page change "Restore into directory" from
"/home/myuser" to "/home"
4. Confirm
5. Next page shows
-----------------------------------------
| Original file/dir: | Restore to: |
| myhost://home/myuser | myhost://home/ |
-----------------------------------------
instead of
--------------------------------------------------
| Original file/dir: | Restore to: |
| myhost://home/myuser/.maildir | myhost://home/ |
--------------------------------------------------
Maybe related?
Any ideas on this issue?
Marcel.
