Hi, How did you change the path for backuppc ? Did you change it in config or during installation ? This usually happens when your backuppc storage directory is not setup properly; atleast that's what I found out while using it. I then used the sf.net version (instead of distro packaged version) and through configure process changed the storage directory.

I am replying to your mail, because i was the one who started the thread about BackupPC_link got error -4 when callingMakeFileLink. Here are some explanations and details 1. I used an rpm to install backuppc which has its path for installation and backup location embeded in it. 2. Due to less knowledge about how backuppc works, i tried to change the path, and thus resulted in the errors which were posted by me. 3. Eventually with the help of list users, i was able to resolve the issue. To make sure you don't mess up things the way i did, i would advise you to install the version from sf.net website. The install allows you to customize the paths all at the configuration/ installation time. Doing this, the errors disappeared for me atleast.

Re: [BackupPC-users] BackupPC_link got error -4 when calling MakeFileLink
I do not recommend one solution or the other, both work. I prefer (2). The configuration is easier to read if you find the mount-point of file-systems directly under /. And, according to the man-pages, --bind is not obsolete, -o bind might be. This documentation comes with the kernel, I consider it official Linux documentation. Thanks, I will change the group ownership of the topDir directory to root (and keep backuppc as owner - backuppc in fact does add directories, it added pool in addition to the already existing cpool and pc directories during the night after my original install). Indeed the wiki is the second place where I look for information - looks like that is part of the general problem of how to find. -- ___ 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/

There isn't a restriction if you do the install yourself. What solution are you proposing exactly? AFAIK BackupPC doesn't care if topDir is on another filesystem or not and how it is mounted. Just make sure the filesystem it's on supports hardlinks and that your backuppc user can access topDir and it should just work. It did for me. If you install backuppc from the sourceforge tarball, you can choose your own topdir during the install procedure and everything is adjusted to use it. In packaged versions already configured to a linux distribution's conventions this step is already done and even though there is a variable setting for it, not everything observes a run-time change correctly - but it may be possible to fix that. -- Les Mikesell lesmikes...@gmail.com -- ___ 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/

Re: [BackupPC-users] BackupPC_link got error -4 when calling MakeFileLink
I fought these messages yesterday. In my case the reason is that topDir - the directory where the backup data is stored - is a separate file-system, and that BackupPC has problems dealing with that situation. Googling provided 2 alternative solutions (there appears to be quite an epidemy of people suffering from this problem): 1. Make /var/lib/backuppc an empty directory (if currently you have data there, start by saving it elsewhere), and than mount your topDir file-system at /var/lib/backuppc (also documented in http://www.cs.umd.edu/~cdunne/projs/backuppc_guide.html). 2. Use the --bind option of mount (the Google reference suggests -o bind, I guess another and probably obsolete flavour of --bind, not documented on my Mandriva platform). I start by mounting my file system for backup data quite traditionally at the mount point /backup, but after that I add an additional mount instruction: mount --bind /backup /var/lib/backuppc That acts like a hard link between /backup and /var/lib/backuppc - you see the same data through either mount point (and, evidently, you must again start by saving any data at /var/lib/backuppc) - and BackupPC appears to be happy, no more error messages. You will probably want to avoid the explicit mount --bind ... instruction: this is done by adding to your /etc/fstab - I placed it directly after the mount /dev/xxx /backup ... instruction - the following line: /backup /var/lib/backuppc none rw,bind 0 0 with the result that the 2 mount points get mounted at boot time. I also changed owner and group of /backup to the backup user - but there I am less sure how correct or imperative that is. I read that a new release (3.1.1) of backuppc is being prepared - short of fixing this problem, it might be a good idea to add a couple of words to the documentation, warning about this restriction in the configurability of the topDir variable.

You will probably want to avoid the explicit mount --bind ... instruction: this is done by adding to your /etc/fstab - I placed it directly after the mount /dev/xxx /backup ... instruction - the following line: /backup /var/lib/backuppc none rw,bind 0 0 with the result that the 2 mount points get mounted at boot time. I also changed owner and group of /backup to the backup user - but there I am less sure how correct or imperative that is. I read that a new release (3.1.1) of backuppc is being prepared - short of fixing this problem, it might be a good idea to add a couple of words to the documentation, warning about this restriction in the configurability of the topDir variable. What solution are you proposing exactly? AFAIK BackupPC doesn't care if topDir is on another filesystem or not and how it is mounted. Just make sure the filesystem it's on supports hardlinks and that your backuppc user can access topDir and it should just work. It did for me.

Hi, Juergen Harms wrote on 2008-12-26 23:46:55 +0100 [Re: [BackupPC-users] BackupPC_link got error -4 when calling?MakeFileLink]: I fought these messages yesterday. In my case the reason is that topDir - the directory where the backup data is stored - is a separate file-system, and that BackupPC has problems dealing with that situation. as Nils said, that is not true. BackupPC has problems with incorrectly changing TopDir. Googling provided 2 alternative solutions It might not be obvious, but the BackupPC wiki goes into some detail on this topic: http://backuppc.wiki.sourceforge.net/change+archive+directory (there appears to be quite an epidemy of people suffering from this problem): There appears to be quite an epidemy of people not consulting the wiki. 2.

Well, you can't change the group to the backup user ;-), but it's correct and I'd say at least recommended too. Once the directories under $TopDir are in place, the backuppc user should not need to create any, but you never know what directories future versions of BackupPC might want to put there. I read that a new release (3.1.1) of backuppc is being prepared - short of fixing this problem, it might be a good idea to add a couple of words to the documentation, warning about this restriction in the configurability of the topDir variable. I believe there *is* a warning in the documentation (though I admit I can't find it right now), and I believe it *will be* fixed in 3.1.1, of which I haven't heard that it is being prepared, though.

Hey Nils, thank you for your answer. I will change the mountpoint as soon as the currently running backup finishes and see if these error messages show up again.

Re: [BackupPC-users] BackupPC_link got error -4 when calling MakeFileLink
It is not generally recommended to change the $TopDIR logical but on Debian it is not really even doable. Debian and Ubuntu have $TopDIR hardcoded to /var/lib/backuppc, just mount your target their either by directly mounting it or using bind. mount -o bind /target /var/lib/backuppc fstab /target /var/lib/backuppc bind 0 0 Nils Breunese (Lemonbit) wrote: Masta Yogi wrote: I installed BackupPC 3.1.0 on a Debian Etch machine and then moved the Topdir to a directory in /mnt/...

Hi to everybody, May anyone, please, help me with the following problem? After full localhost backup (many gigabyte) I got the following error: BackupPC_link got error -4 when calling MakeFileLink(/data/BackupPC/pc/localhost/1/f%2f/famule/fIncoming/attrib, cb5bab76b89c25b11c8f575a567b571a, 1) I checked the following facts: 1) /data/BackupPC/pc/localhost/1/f%2f/famule/fIncoming/attrib is in the same file system than /data/BackupPC/cpool 2) The directory cpool can be written by backuppc. On the other hand it is completely empty (no subdirectory /c/b/5) and the ln command cannot work because the subdirectory are not created ln /data/BackupPC/pc/localhost/1/f%2f/famule/fIncoming/attrib /data/BackupPC/cpool/c/b/5/cb5bab76b89c25b11c8f575a567b571a 3) The disk is new with many thousand of inode.

Looks like you have checked all the right things. I can't explain this. Here's the code: mkpath($newDir, 0, 0777) if ( !-d $newDir ); return -4 if ( !link($name, $rawFile) ); It creates the cpool path first and then adds the hardlink. Perhaps you can add some debug statements around this code to try to figure out why the mkpath doesn't work. Craig - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [BackupPC-users] BackupPC_link got error -4
Ahhh, that would make sense (I guess as still learning Linux). I installed Debian on one smallish sized drive using ext3, tested backupPC, decided to go further but needed to add additional drive space. In doing so I ran across a couple comments somewhere about using ReiserFS instead of ext2 or ext3. I installed the second drive and formatted it with ReiserFS. I moved the /var/lib/backuppc/pc to the second drive and symbolic linked it. I will try moving the cpool to the same drive and symbolic link that one as well. I am open to any better suggestions or any thoughts about partition types to use. Luckily I have not gotten far so I can always redo things if necessary.
