I am backing up parts of my computer with DD, and i was wondering if there was a quick way to split the files created into 4.4GB sized files that will fit onto a DVD. Anyone have any idea of how to do this?
View 6 RepliesI'm just setting up a partition on a seperate HDD in my system. I plan to use the partition to backup the important files on my main HDD (to guard against HD crash).
The question I have is about where would be the typical location to auto mount this partition? Which would it be normal to go for:
1. /backup/
2. /media/backup/
3. /mnt/backup/
4. /home/chris/backup/
I'm trying to upload my tar'ed site to server but I have upload limit. My ftp program extracts tar after uploading it. How do I split this one tar into two so I could upload one tar and let it extract itself, and then upload second one and let it extract itself too?

I'm amazed I couldn't find anything in my searches on this specifically.What I want is to go from a Gentoo rescue CD to a restored system as easily as possible.I tried rsync over gmailfs but that just froze. I can't really see that working too well anyway.

I used split -b 32m "file.bz2" "file.bz2.part-" to split a file and it created more than 50 parts. From googling, the way I found to reassemble the parts is to cat file.bz2.part-aa file.bz2.part-ab > file.bz2, while enumerating all the 50+ parts. Is there an easier way to reassemble the parts wherein I no longer need to list all those parts explicitly?

Today encoders are getting smarter. They can compress Blu ray similar quality in 700MB. It seems header of video file contain info about frame rate, audio/video encoder etc. which can't be guessed. In MPEG audio , every part of file is independently playable. If a movie is binary split into 6 parts & I don't have the first part then it is unplayable.
Code:
example
ls
-rwxrwxrwx 1 root root 280M 2010-12-07 20:23 irn2-cd1.mkv
-rwxrwxrwx 1 root root 50M 2011-05-26 13:09 last-50M-cd2
-rwxrwxrwx 1 root root 50M 2011-05-26 13:44 first-50M-cd1
file *
first-50M-cd1: Matroska data
last-50M-cd2: data
irn2-cd1.mkv: Matroska data
I guess in most cases when extracting a tar achive ,we will get a directory with the same name as the archive file but different suffix. but in some unlucky case, as I met today, after extract a tar bar I find lots of files spread in the working directory, which is really nuisance.so what I want to learn from you is that how can I move thoes newly created files ? I know it should be some "find plus rm" fancy approch there, but I don't know exactly how.
View 3 Replies View RelatedI created a directory somewhere with permissions rwxrwxr-x so that other users in my group can create files and directories in it.
I do need to be able to delete the contents in this "public" directory, but it seems that while I am able to remove any files in this directory I cannot remove and subdirectories under it.
Is there a way to remove such subdirectories owned by others under a directory owned by me?
With the find command it is easy to find files that have been modified or accessed within a given period. When a file is created, the acesss time is the same as the modify time. But as soon it is accessed (read), the access time changes, but the modify time does not. I need to find files that been accessed at all, ie. files which have access time newer than modify time. How do I do that?
View 2 Replies View RelatedHow to find and list files and directories present the current directory which were created in, say, years 2005, 2006, and 2009 and then move them to some other location, for example, /backup. Yes, I need to list them and move simultaneously. We can use:
Code:
find . -mtime n {};
but that n is troublesome for me to figure out files/directories created in years 2005, 2006, and 2009, for instance. Is there any way to match exactly by Year Value rather than calulating the "n" (days * 24 Hours)?

View 2 Replies View RelatedI am trying to create an RPM package. However when the RPM package installs, it need to skip some files that might have been created by the user after the last installation and use of the program. Is there a way to build RPM package that just skips the user created content in the installation dir.
For example:
lets say my RPM package creates the following dir and creates files required by my application, say .app files.
/ppm/config/
However the user may also create a few .xml files in the same dir. How will I package my program that will not delete the .xml files from the above dir and will just create the application files (.app files).
I have ext3 partition mounted on /mnt/shared/ as follows
Code:
Permissions above are of the actual mounted fs.
Goal is to have all files created on the fs
1) to belong to group 'users'
2) to have this groups permissions set to rw (rwx for directories) so that all users who belong to group 'users' have full read/write access to data and everyone else to have only read access.
Now because of setgid bit (s) in group permissions every file created has group 'users' and additionally setgid bit is set for directories. Because every users umask by default (on my system) is set to 0022 all created files will have permissions 644 for ordinary files and 755 for directories.
Net result of above means that users A and B who both belong to group 'users' won't be able to modify files created by the other.
So how can I make files created on the fs to be created always with umask 0002 WITHOUT changing default umask for users that is used elsewhere (like in their home directory) ?

View 1 Replies View RelatedI have a file of +1 1GB in size. I want to split it in either 100MB rar files or 100MB zip files.
Anybody know what command I need for this?
Please keep it simple, I'm very new to linux. So I'm hoping somebody can give me a command in the lines of "blabla "put file name here" "put file size here" "put folder to rar/zip" here.
I have a situation where a directory has about 1.5 million files in it. On an hourly basis, I want to be able to find any files that have changed in the last hour, compress them, encrypt them and then copy them to both a local backup machine and an off site backup.
Is there any kind of utility or kernel module that creates some type of log of modified files? I know I can use find, but the search for -mtime in this directory takes quite a while and will not suffice for an hourly backup.
if there an application which does the following:
1. I have a laptop with an internal 200GB HD.
2. I run the application & it creates a list of all files (size & time-stamp) without actually storing them. Let's call this the "snapshot list".
3. I update some of the files on the laptop.
4. Now I run the application & it only copies the files which have changed on the laptop, that have different size/time-stamp from the snapshot list, onto some external media, such as a memory card. Of course, the files should be copied onto their proper location in the directory tree & not just pile up in one place.
Why is this useful? although the laptop has a 200GB HD I typically only update a small number of files, whose total size is maybe 10MB or so. If I could only backup those which have changed, I could do this with a tiny SD card instead of lugging around an external usb HD.
I am using rsync to create rotating snapshot style backups of my web files and sending them via SSH to a remote location in order to burn them for offsite storage. This is all working perfect. The remote machine is a Windows Server 2003 which has data that I combine with my web files before burning. I have cygwin installed on the remote server in order to archive and compress the entire backup using tar. (This is not a post about cygwin, I just thought I would mention it in case anyone was wondering how I was running Linux commands after transferring it to the Windows box). After compression, the backup is over 12gb. The next step in my process is to split this tar.gz file into smaller chunks in order to burn them to DVDs. I use dual layer DVDs which are 8.5gb storage size.
I also use cygwin to split the tar.gz into multiple 2gb files using the split command. When I burn them, I only put 3 files on each disk totaling 6gb to leave some padding in case this was a problem. The burn completes and says successful, although it errors out when in verification. I have tried this multiple times and it seems to fail verification at the same point every time which leads me to believe that it has something to do with the data. I have also done tests such as creating smaller backups with completely different data and brning that to a CD-R which worked fine, so I'm convinced this process can work, I just cant get it to work in the right situation. I have also tried burning one of the 7 split files to a dual DVD which also worked fine. I'm wondering if their is a chunk of data that is causing this problem in one of the other split files?
