Re: Can Debian Backup ntfs File System?
The client who wouldn't back up because she didn't want to spend any money, found herself faced with a dead motherboard. She expected me to have a new computer up and running with all her data on it within a few hours. (Note that diagnosis was also to be included in the short timespan, as was procurement.) It actually took me many hours to recover the data, which I did successfully. Far from being grateful, she made my life a misery for taking too long. Had it been her hard drive that was dead, she might well have lost the data. Lisi For that kind of people I charge 30% more, that’s tax for my nerves.

Re: Can Debian Backup ntfs File System?
An operating system should have reliable backup policies built-in; for example, it should backup the entire /home subtree to rewritable DVDs, or a network share, on a weekly basis. When installing the system, the user should be asked where to and how often the backups should be made, just as (s)he is asked for the time zone and the language to be used. Without this info, the installation should simply refuse to go on. --- And where do these magical DVD-Rs to write to come from? How many users rush past automated security and warning protocols before acquiring viruses and malware... Simply put, make something idiot proof, they will make a bigger better idiot. You can't protect and shelter people from the big bad world forever. And yes, I do most of my major car repairs, no I'm not a mechanic. I can cook, clean, and sew, and I'm not a woman. I constantly study survival techniques and look to become proficient at procuring my own food. There is NO excuse for spending countless hours in front of the idiot box and being completely unaware of even the basic functionalities of the things in our world. TeddyB

Someone else maintains it, keeps it running, and all they have to do is use it. My dad sees it this way, at least, and I'm guessing he's not the only one. Only until he experiences the pain of lost data will he change his ways. There are probably others like this.

And common sense has to be applied for all the aspects in the life, not just "computers". Let me use an example to illustrate this. Imagine there is an elderly and experienced writer that is still using his old and trustworthy Olivetti typing machine for his work. He has to publish a new book before the end of this year and he starts by making some drafts and manual annotations about the book's main story. Then, he starts typing the firsts chapters of the book with his Olivetti, and reaches 100 pages... At this point, the writer can: a) Do nothing and wait for the best, he is a very organized person and thinks nothing can happen to the hundred pages he already wrote. b) Go to the store and make a couple of photocopies, just in case. Well, this is the same diatribe that every computer user has to face for his data but still, this has nothing to do with the user's computer abilities (there are many easy -and automated- ways for dealing with this) but his interest. The same happens with the elderly writer: there is no need to be the smartest people in the world nor being a literate in any specific field to care about your work (and your time) and be careful enough to prevent any disaster. So, no... people who pretend to give "value" to his data and has not performed a single backup copy of his files in years, I just simply say, "heck, no, those files weren't that important". >> NTFS is quite robust.

No, she didn't. She thought that because she had used the program Picasa, then Picasa would magically produce her 'photos. She did not have them online. There was only the one copy on her computer.

I had explained in words of one syllable till I was blue in the face, and her niece bought her a pen drive and backed all the then current pictures up. She also explained in words of one syllable.

I understand that today's Linux drivers are better in this regard, but just a few years ago one would not want to write often to an NTFS partition without booting it into Windows occasionally for some error checking.

Yes, I see the point. I have been working in IT tech. support for many years and finally reached the conclusion there are two kinds of people: 1) those who care about what they are doing and want to learn -they can be savvier or dummier but at least they demonstrate interest- and 2) those who treat their computers the same as a fridge or cleaning vacuum :-) For 1) I always try to give them the proper information, at least a "jump point" from where to start digging and also answer their questions whatever they are.

If you can't even copy/paste or dump it to another source you'll have to deal with your "fragile" hardware. And IIRC, hard disk was visible and even mountable but if you still think there is a hardware failure, then better use the manufacturer's disk utilities to check hard disk integrity (they run from DOS floppy or live ISO image).

Last backup was from a year ago, that should give you some hints about how valuable is data for the user. NTFS is quite robust.

Maybe they cannot solve the > problem but won't aggravate it either. And before "wiping out" the hard > disk, I think it is at least worth a try. The point I wanted to make is the following: Defrag shifts parts of the files -- and in order to do so, it OVERWRITES unused parts of the disk. Now: as soon as the filesystem is corrupted, one can't trust anymore in the information which parts are "unused" -- so it can happen that defrag (or any other tool which writs on the disk) overwrites file-informations, which belong to a "lost" file, but which are believed to be "free" and "unused" by the filesystem. In my opinion, this danger is not limited to ntfs, but exists in every filesystem: as soon as the filesystem is corrupted, one can't guarantee that the blocks marked as "free" don't contain usefull information -- and that's why I wouldn't write anything on the partition! A similiar point is true for scandisk / chkdsk: Again, independent on the filesystem: Once the filesystem is corrupted, the recovery tool has to make assumptions about what is the "correct" information -- and if it makes the wrong assumption, it WILL destroy data. For example: How can chkdsk guarantee that, whenever it writes some information on the disk, it uses a truely "free" part of the disc? maybe on this place was a piece of an important file, which was lost by the file-system corruption? Of course the question is, how important the data are -- is it worth the effort to first create a copy of the partition and then to work on the copy?

I've never heard neither seen that before and have worked with ntfs volumes during many years. In fact, I've managed to "restore to live" windows systems that were unable to boot up by following that procedure (even an unexpected shutdown can make the OS to be unbootable -system files tend to become easily corrupted- and checking the file system structure solves the issue). Scan disk (chkdsk) and defrag are the standard and recommended tools for dealing with MS file systems problems. Maybe they cannot solve the problem but won't aggravate it either. And before "wiping out" the hard disk, I think it is at least worth a try. Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

(I think it's in the 'testdisk' package). It can find files that the filesystem doesn't know is there. This includes some files that have been deleted. -Rob -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

I recovered all but about 35 files from a Vista installation on a laptop which had been dropped, and the drive had hard errors, presumably where the heads bounced. Lenny is *the* server distribution, but it isn't especially up-to-date, and NTFS is a moving target. -- Joe -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

But that is extremly dangerous...: you risk to loose/destroy informations on the damaged filesystem (nobody guarantees, that scandisk is not destroying data...). And especially defrag: this WILL destroy data, which are in lost files (=sectors of the harddisk which seem to be free according to the file system...). So, as Thierry already proposed: Make first a copy of the complete partition (using "dd" and ignoring the filesystem) and then work on the copy. And when you mount the "original" partition: do it ONLY with "read-only" flag -- in order not to destroy data! Of course the question is: How important are the data, and how much time do you want to invest in order to recover them? Using "cp" or "rsync" you alread can copy some data... After that, you should first try to determine WHICH files you need -- and where the messages about incorrect inodes appear: for example, it is absolutely useless to try to recover the system-file e.g. in /windows/system32 -- you only have to worry about the data-files created by your daughter. Maybe those (at least some of them) can be copied without any problems? As "last resort" you can try tools like "scrounge-ntfs" -- this is a debian package to rescue data from damaged NTFS-Filesystems. But be careful: each time you write something on the filesystem (e.g.: also by using defrag or scandisc from windows) you risk to loose data and make recovery harder or even impossible, so: work on a copy of the disk!)

I would try with plain copy/paste. If that also fails, put the disk into external USB case, attach it to another windows xp (or later) box and perform there the common file system diagnostic tasks (scan disk and defrag).

Can Debian Backup ntfs File System?
Situation: My daughter works for a bank and must use Microsoft to work at home. Yesterday the system would not boot - no safe mode, no nothing, just return to loading bios. The machine is an HP desktop which came preloaded with Windows XP Professional. As instructed we made a recovery disk and some backup files. I now find the recovery disk will only wipe the hard drive clean and reinstall XP. The backup files are a year out of date. At the time she bought the machine I installed a second hard drive, installed Lenny and configured mbr for dual boot. Yesterday I edited fstab to include a mount point for the Windows primary partition setting the file type to auto and was able to mount the partition and read files. Hoping to save the recent information I tried rsync -vr /c /c_bkup. This didn't work, many messages about incorrect nodes. Is there any chance of recovering usable files before we wipe out her hard drive? Tom -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
