I just read in my Linux+ resources that it is not a wise idea to compress tar files with gzip if my tape drive supports compression. In addition, the resources mention that using gzip for tar files runs the risk of data lost if an error occurs with the compression.
Does anyone compress tar files for major backups/restore policies?
I am trying to compress a folder by right clicking and selecting Compress...I get the following error:
An error occurred while adding files to the archive.No such file or directory
I want the folder and its content to be compressed to a .ZIP file which is natively accessible by Windows.
When I right click on a file and click "compress" I get a .zip file that is exactly the same size as the original file.

How do I compress then encrypt those files, and can I add any commands that will do this to my existing bash script?
I am running Ubuntu 10.04
i have noticed that if right click on many files types for instance iso files i don't have the option to store them in compress files at all i have one iso file now that i want to compress and split to three parts so i could upload it but as i said right click on the file don't helpbecause i don't have the option there so what can i do?
View 4 Replies View RelatedIs there is anyway, with tar, zip, gzip, or any file compression type to compress without causing high CPU. In other words, limit how hard the CPU works to compress it? Of course I understand that this would cause the compression to take longer but time isn't too big of a concern.
View 3 Replies View RelatedToday I tried to compress some folders containing backup files from last year. I right-clicked on the folders and selected compress as tar.gz. I let it work, and found that hours later, the folders were still compressing. How long is it supposed to take, anyway? I was trying to compress the two sets of backups simultaneously; together they're around 1.5 GB. They have many subdirectories.

The svn returns output of all the file names from the repository and in the end it says: revision number xxxxx. i need to get this number and then rename the tar.gz to it. how do i save the output to a variable and get this number.
This is the script:

I download a lot of files that have been compressed into separate pieces by winrar, so that a 4gb file will be shown as dozen or so 93mb peices. In windows, using winrar, extracting them was rather easy but in Kubuntu whatever default program is being used throws a fit. In a perfect world I would want to get a open source alternative from synaptic, alternatively anything I can download in RPM I can eventually figure out. I want to avoid trying to get winrar working under wine.

Here's what I have planned:
machine: Core 2 Duo E8400, 8GB DDR2, 60GB SSD OS drive, ATI 4650 video card, other storage is flexible (I have 3 1TB drives and 4 750GB drives around that can be used in this machine.)
uses: HTPC, Network Storage, VMWare server host: SMTP, FTP server, and Web server virtual machines
I've figured out how to do much of this, but I haven't figured out how to do backups in Linux. I've been spoiled with Windows, with the built in backup system so simple to use. I find myself overwhelmed with the array of backup software, and unable to determine which to use. none of them seem to do everything I need them to do, but some come close, I think. I'm hoping someone here can help me out in figuring out which program to use and how to use it.
Here is what I need the backup software to do:
1. scheduled unattended backups, with alerts if the backups fail
2. a weekly full backup with incremental every 12 hours
3. removing the old backups when the new full backup runs, I would prefer to keep 2 weeks of backups, but that's not necessary
4. a GUI would be preferable, since my arthritic fingers don't always do as I want them to do. I typo things a lot, and the label worn off my backspace can attest to that.
How do you get Rsync to do incremental backups rather than full backups? At the moment I have a script that will create a backup folder (if it doesnt already exist) then copy the source files into the backup directory with the command
rsync $VERBOSE --exclude=$TARGET/ $EXCLUDE --exclude '/Ls-wtgl1c8/**' -rt --delete $source/ $TARGET/$source/ >> $LOG_FILE
Target is where the files will be backed up to Sources is the dir(s) to be backed up Exclude files is the list of files not to backup
log file is where the output will be saved to. At the moment it only does full backups, but I would only like to do incremental, how would this be achieved? Am I missing out an option in the Rsync that is required.
I have an ubuntu (8.04.3) server where I use bacula to make backups of the files stored on the server. Ive been trying to find a solution (with no luck) trying to succesfully implement the following:-
A Backup tape for each day of the week besides Thurs which is resused on a weekly basis. For the thursday tapes we have a backup tape corresponding to the week number that the thursday falls so for the first thursday of the month it would be ThursOne For example. These tapes are resued on a monthly basis. We then have a monthly tape that is used on the last thursday of the month. These tapes will be resused on a yearly basis.
Another requirement is just in case a tape is accidently not changed a backup should still occur regardless of what tape is in the drive (so if its tuesday and mondays tape is still in the tape drive it should rewrite that tape).
I did have this successfully set up where the tape was appended after each use rather than being recycled after the nightly backup. But then after a few weeks I would have to manually purge tapes when they became full (which isnt ideal - as Im not always in the office so in my absence it may be that a backup may not take place), so have been playing around and have now got the tapes to be marked as used after a max of 2 jobs (so the backup of the files and the catalog of the night). I also added this line 'Recycle Current Volume = yes' so that it would hopefully recycle the volume in the drive.
However what I am finding is that the tape that should be recycled is not, but in yesterday case the Mondays tape was recycled rather than the Tuesday although Mondays was the last written so Im not even sure why it choose to recycle this tape.

View 2 Replies View RelatedI need to recreate my initrd.img after having extracted its contents. Bash by itself; pointing me to similar threads in this forum and google are useless to me and a waste of everyone's time as that has all failed. I need a working example. Apparently, I am supposed to use this bash command (s): "zcat ../initrd.gz | cpio -i -d." The preceding command is unintelligible to me. I cannot compress the initrd.img file and folders back into an initrd.gz file with a compression level of 9, so that I can rename with a .img extension.
My understanding of recompressing folders back into the initrd.img: Google and this forum all point to bash involving either zcat or cpio and then gzip with a compression level of 9. However, I require exacting instructions for using these commands to compress the folders that have been extracted from the initrd.img back into one homogenous initrd.gz archive so that that the created initrd.gz can be renamed initrd.img
Note: posting bash without that an example is a waste of everyone's time as I found that on Google and it was useless as I lack the requisite computer science degree or years of Linux guru experience needed to figure out how to specify the arguements proprerly. What I need is a working example, not just bash.
Note2: To save time, the answer to why I need to edit the initrd.img is this: Two different utilities (based upon the same parent system & kernel) use the same initrd and the same file paths. When they are installed on separate partitions and the one farthest from the mbr is selected for boot, it will begin to boot and then switch to the one closest to the mbr, which results in a failed boot. If one is removed, the other boots fine, so it's not a menu.lst or a lilo config problem.
