Actually, the decision to switch from reiser to ext3 as the default filesystem in openSUSE 10.2 is not related to Hans Reiser being arrested on murder charges. Most of the maintenance of reiser3 filesystem was being done by SUSE engineering,

Okay, that makes sense. I did an informal test. Under my music folder, I have 32G of music files (mostly mp3 and ogg) which - under reiser - would take forever to open. It seems under ext3 that it takes less time. Thanks for the answer. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Is undelete available on opensuse? How do i recover some files that were mistakenly deleted?

Generally if you delete files from Konqueror they end up in the trash bin, and can be restored, unless you hold the shift key while pressing the delete key. If you issued a rm filename from hte command line, I do not know if these can be recovered. AFAIK if you delete a file from inside an application, it too is toast.

Crap! I ran the rm from the command line and using reiser. Thanks for the reply

People have been known to replace the "rm" command with a script or shell procedure that moves the target files to a "trash" directory instead of deleting them outright. It still doesn't help with, e.g, and application's "Save as..." function that overwrites an existing file, but it's something.

in this situation, no file can be retreived by no system (even windows).

That's not completely true... old Vax VMS file names had also a version number. You could have "file.ext;1", "...;2", etc, so you could go back and retrieve an older version of the file you were working with. Nice feature, except if the admin had limited the number of versions to two or three... which my teacher did.

And there's a even a very limited counterpart in the Gnu tools: The "cp" command's --backup and related options. You can also set up rdiff-backup to periodically make incremental snapshots of select portions of your file system. But of course, a real backup and archive system is an important ingredient in any data safety setup.

I remember that. OOo also has this feature. What I talk about is different: it uses one file for each version, with a version field in the file name managed directly by the operating system, not the application program. It is also different from external backup, as it is automatic and continuous, and can be affected by disk failure, of course.

The newer Mac OS X does / will do this, AIUI. Apple call it "time machine". When you turn it on the, e.g., finder window becomes transparent, and you see a stream of windows into the past which you can flip through to get the file version you want. When you plug in an external hard disk and say you want to use it for backup, all the old copies are duplicated to it. I've only seen the demo of this, however. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Well, "data safety" setup is difficult for home use. However, as has been pointed out before, usb-storage is cheap. For example, I use rsnapshot to do full backups, using symlinks. That's smart, because it works automatically, and it in fact "only safes" differential data, while still maintaining a "full backup anytime" structure that makes it ease to revert to previous (backup-)versions. You can configure it to backup yearly, monthly, daily, hourly, minutely..., whatever you need, according to your needs.

Sure, but again, if you are prone to "last hour deletions" or if your work is valuable to you in any other respect, simply do a "quarter-hourly"-backup and the worst that can happen is that you loose 15min of your valuable time. Another option could be subversion, if version-management really matters.

I'm talking of a versioning method handled directly and transparently by the operating system. It is not a backup system, you still need them.

I know we can use dozens of methods to use instead, but that is not what I'm talking about, and none can compare with a versioning filesystem.

Well... Sun's ZFS does this. The filesystem snapshot thing is pretty slick... actually, I think it's more than slick, but I'm often distracted by shiny objects so.... :-) Kinda sucks that the Linux implementation has been started in FUSE instead of in the Kernel... but the license issues kinda force it to userspace. http://zfs-on-fuse.blogspot.com/ C. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

In comparison to what? In comparison to equivalent HD in a USB drive caddy maybe. In comparison to 10/20Gb tape definitely. In comparison to a DVD definitely not.

In comparison to anything that can be considered a backup media. DVDs don't count for me. While they are larger than CDs, I cannot think of an automated DVD changer, that could automatically do my backups for me. And "automatical, no user intervention required" imho is, what differentiates "sorry no backup, I forgot" from "There are so may backups, which day of last week do I think, I will need to restore this damned file?".

You can get the advantange of random RW which is damn difficult on most media orientated DVD/CD devices and media. (DVD-RAM is possible if can find the media and an appropriate device)

And pay the prize ;-), while still having just DVD capacity. I agree it would be cheaper and transparent to the user. Anyone know how do CD packetwriting in Linux? [...rsnapshot does basically anything that you will ever need...]

This is a good serious professional tool, but unfortunately to get the most out it you need to be a good serious professional.

ok. But there is good news, to- To get the least of it, i.e. do an automated, regularly scheduled backup of one machine to an usb connected harddrive, you need much less than an afternoon. Very cheap in comparison to a loss of valuable data. I admit that it took me MUCH longer to figure out how to include my windows machines transparently into the rsnapshot backup that runs on my Linux machine. But this only shows that there is nmuch more potential in it, than most people can get from a paid solution. And seriously, a non-professional tool will have a hard time to do professionl backups? I do not think so. Remember: The User never ever needs to know that her backup is running..... It simply works... Moreover it is free as in beer and speech and it even saves transparently all the valuable data from your windows colleages. What more can you expect from a free solution?

Well, while this may be true, I would think that most home users will be ok with an automated, regularly scheduled backup of different hours/days,weeks/monthes/years... to external media.

Yep but with what? rsnapshot, doing backups to usb-drive(s)? ;-)

I think Verity Stobs summarises the situation of machine deterioration rather succinctly in the link below...

...

http://www.ddj.com/184405140

I am certain that someone can come up with equivalent metrics for linux:-)

Agreed! Nevertheless, I prefer to do what I can to save my data, just now! And I probably will need to restore it or a portion before my machine deteriorates.

...

In case that does not suffice, you might add a few more portable usb-harddisks, that you store externally at a remote location away from your computer.

As in many cases this would lead to a additional 40% -50% of home user machine cost in backup storage so I doubt it is a goer. They spend the same much in DVDs in the end but it not an up front financial jolt so more likely to be born.

Agreed! But it usually gets much more "go" after a serious data loss.;-))From my perspective, there is a harmless question: What happens, if your harddisk dies now? Nearly always this helps to easily calculate a fair prize for a backup strategy. If not, well then let people do what they prefer to do. They'll come back, sooner or later ;-))

...

If that does not do the trick, imho your needs are ripe for a professional backup solution that needs a professional budget, accordingly.

The difficulty is many of the current home solutions are dire. GHOST has degenerated from being something very useful to both windows and linux users to being a temperamental monster. Most others solutions require some understanding of backup cycles, and systems management.

Imho this depends. If you want to have a Ghost lookalike, you might use partimage. For backup, I prefer solutions that work transparently, and smartly, anytime, everytime. If this requires understanding of backup cycles and systems management, it might not be ideal for Joe Homeuser. However, once again, he will listen carefully, when you talk to him about the value of his digital photographs, his letters, his projects, his MP3 digitized vinyl records and his Mails........

On windows, I made sure that any user "ONLY" uses d:\data or d:\Eigene Dateien\username to store her files. Notes: 1. I personally used cwrsync on my windows machine to have a working rsync server without any additional cygwin things. Thats much quicker! 2. Had I had access to theses things before doing it, it might have taken much less time and hassle. 3.

backup forn home user can only be acheived on a one by one thinking.

let me give an example:

my son spend much time downloading films and games from the net (I know it's not fair, but are your sure your son don't?)

Currently he is five years old, but that will change ;-))) - it's just an example

He got a 200Gb internal drive.

ok! If that is the only drive he has, I doubt that all 200GB are "data" in the sense of "valuable data that you definitely do not want to loose". However, for purposes of simplicity, lets assume that your son has data with a volume of 200GB (or less), that needs to be backed up regularly.

If I had to backup all and every file on his computer, I should have 100 Tb of usb drives... You might have ignored the essence of rsnapshot and similar solutions. The beauty of these solutions is that backups are done by using symlinks.

Lets see how this basically works and what you get as a result: ===This is how it works:===== (assuming that you are doing a simple daily backup. In reality, you most probably will want to do weekly and monthly backups, as well) : day1: 200GB are backed up to the usb drive day2: just the difference from day2 to day1 is backed up to the usbdrive day3: just the difference from day3 to day2 is backed up to the usbdrive day4: just the difference, you guess it. ... In fact that means that your usb drive will "only" need to accomodate 200GB+ "a little more". Ex 300GB will most likely do for a VERY long time. Now comes the magic! ====This is how it looks like on your usb-drive with Konqueror===== root of usbdrive -folder "day1", including all the data from day1 -folder "day2", including all the data that you had (saved) on day 2 -folder "day3", including, all the data that you had (saved) on day 3 -folder "day4", you guess it.... ... As a result, --you will have a full week of daily backups that you can restore from, either on a per file basis or as a whole. --But you only need to accomodate your data size plus "slightly more", because the "full backup any day" is done by using symlinks, so you profit from the fact, that a very lare percentage of your data will most likely be identical from a given day to the next..... Now compare this to a more conventional backup strategy of doing a real "full backup any day", where you need to accomodate space that you will easily and frustratingly multiply on your own. And compare to the convential method of doing a full backup, followed by "differential" backups. This will save you space but you will stop to like it in the case a restore will be needed. ;-))

to have consistent backup, one must look at his own kind of work.

Definitely!

rigth now I work mostly by browser on a web site not of my own. Hope simply the owner makes a backup. On an other site I'm the owner, but my work is on pmwiki, very small flat files app. The hole web site is under 100Mo and the usefull pmwiki less than 10Mb, so tar file copied on ma server account and on my persobnal computer. very soon, I will have a rsync system, no need of diff...

That's ok, as long as it is working for you. Btw. rsnapshot is in fact rsync, with the added benefit that you do not need to care on your own for multiple generations of your rsynced data.

I try to keep my data folders under 4Gb large and write them to dvd frequently

all the other data is saved when created.

and my personal data (photos...) are duplicated on web servers, free from fire or water.

That's much better since a local backup solution will hardly be protected against fire, water or theft.... I never intended to indicate that rsnapshot (and other solutions like this) are the cure for any given backup problem. They are not! And there is much more to a professional backup strategy than an usb-disk ;-)))) However I use it and have found it beneficial for my given problem that I wanted to have a cheap, quick, automated backup at home, that saves space and executes my backups locally to a locally attached usb-disk.

day1: 200GB are backed up to the usb drive

External usb hard drives are very convenient, but they are not reliable, unfortunately. They are exposed to handling, for instance, and a HD should not be even moved while spinning.

Then, the chipsets used by those boxes are cheap and incomplete, they don't have the necessary functions to use SMART and thus asses the drive health.

It is a very convenient way of adding large storage capacity which you can then move out to a cupboard or safe, but in fact they can and do die on you at the most unexpected moment.

I understand Google did a paper on disk drives. They found that SMART was not a very good predictor in determining drive health. I think it was a three year study on their drive failures at Google.

You might want to consider doing full backups once a month and weekly incremental.

In his case, it is much more efficient to do manual backups, choosing exactly what to copy and when. They are quite large files. Even if you only change the name of a video file sized one gigabyte, the incremental backup program will save a full copy of that file, for instance. The next day he edits the tittles of an scene, and bang, it would save the whole file again. If the video editing takes, say, a week, he may backup the huge temporary files to another internal disk, temporarily, and then save the final product to the final media and/or permanent backup.

rsnapshot, doing backups to usb-drive(s)? ;-) [...] ===This is how it works:===== [...] --you will have a full week of daily backups that you can restore from, either on a per file basis or as a whole. --But you only need to accomodate your data size plus "slightly more", because the "full backup any day" is done by using symlinks, so you profit from the fact, that a very lare percentage of your data will most likely be identical from a given day to the next.....

That is just great! SUSE contains rsnapshot (I just had to go and install it immediately and start learning). Now if the great SUSE developers would have just more time and maybe implement a YaST GUI for that, you could suddenly have a SUSE Time Machine! Maybe even before OS X will have it. (Ok, yes, the OS X GUI for it is ... how should I put it... lot's of eye candy. You could get the job done with less of that I'm sure :-) -- HG. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
