General :: Tar Backup File Keeps Growing?

Jan 7, 2010

I am new to Linux. I am using tar to backup my emails to a server. I would like to automate this process to routinely backup my emails periodicly, however, i keep running into a problem: I start in the dir I would like to create the tar file (dir size = 240MB). I enter the following command

tar cf bup.mail.llc.tar "/Users/d/Library/Mail/INBOX.mbox/Messages"
file size = 234MB

When I would like to backup my emails into the previously created tar file I use the following command:

tar uf bup.mail.llc.tar "/Users/d/Library/Mail/INBOX.mbox/Messages"file size = 462MB The backup command works, except the size of the original tar file grows, around twice the size. When I extract the updated tar file (file size = 462MB), the unarchived file is 240MB the same size as the original directory.

Why does the size of the tar keep growing each time i perform 'tar uf'?? I don't understand this

Debian :: Backup Purge Script - `/mnt/backup/subfolder': No Such File Or Directory

Nov 10, 2010

This script simply deletes files older than a certain age (in this case 7 days) from a certain location; I use it to purge old backups nightly, and it works as expected:

# delete backups older than 7 days
find /mnt/backup/*  -mtime +7 -exec rm -Rf {} ;

The problem is, every morning I get an email with an error message something like this:

find: `/mnt/backup/subfolder': No such file or directory

General :: Tools To Identify A Growing Disk Space?

Sep 30, 2010

currently my disk-space is growing very-very fast and in the same time I have a very limited amount of it.Last time I had this kind of problem, I had MySql persistence replication is on and disabling the feature fix the problem. I don't know what happened between now and then, the space is shrinking rapidly (600Meg in couple of days) and I only downloaded files for less than 10Meg in the same period.

Could anybody give me a pointer to a tool that can oversee growing directories or files or maybe a script that able to do this (possibly involving Cron). I try using "Find" but I cannot find any files that are suspiciously growing. I suspect it's a directory that is growing, but I don't know.

General :: Create A Shell Script To Move Only Files Which Has Stopped Growing?

Jul 20, 2009

An external service I dont manage pushes mediafiles into a shared directory on my server. I need to move these files into their correct directories automatically. The problem is that if I run my script as a cronjob once every 3 minutes, I notice that the script copies files which are still on their way into my server. So I need to figure out how to have the script check that the files are complete (done downloading) before the script moves the files. This is what I got so far:

Code:

#!/bin/sh
# Script by proximity 280709.
# Locate correct directory

General :: SSD Backup - NFS Stale File Handle

Oct 19, 2009

I did a backup of the ssd on my eeepc using the following command from a Linux Mint on a USB key:
dd if=/dev/sda1 of=/media/disk/eeepc_save/SYSTEM/system.bck
(/media/disk in an external USB disk)

I deleted the ext2 partition using GPartEd on live USB key and created it back. I rebooted Linux Mint and restored the filesystem using the opposite command :
dd if=/media/disk/eeepc_save/SYSTEM/system.bck of=/dev/sda1

I mounted /dev/sda1 and when I "ls" the root directory, I get several "NFS stale file handle" messages concerning directories (/dev and other). I tried "e2fsck -y", had a bundle of corrections that resulted in the deletion of the directories. I don't use NFS. I did the same for the user filesystem and had no problem (it's an ext3 partition). The two filesystems are the ones that came with the original Xandros installed on my eeepc and that were mounted with union-fs.

General :: Backup Large File To Multiple DVDs

Nov 2, 2009

I work for a school consulting company.We helped a school deploy about 1500 computers.The computers have windows XP but we have been using G4L for the restore partition on the drives.So far the software works great. We did however run into a problem in that many of the computers we deployed are missing the restore partition. The reason they are missing is long and convoluted and not really that important. What I have been charged to do is try and fix the restore partition problem. One solution that I had, which im not even sure if it will work, was to backup the recovery file, that g4l created, to DVD and write a basic script to recreate the partition and then copy the file over. This process would need to be as automated as possible since this disc will be inserted by the end user(the students). The backup file that g4l created is 5.9GB so it wont fit on just one disc and Dual layer discs are too expensive to use for this project, so the file will either need to be compressed again (not sure if that's a good idea or not) or split across two DVD's.

I have searched the forums here and I was not able to find anything to fix this problem. I was able to find some info on splitting files across two discs but im not sure how to use that to fix my problem.

General :: Open Source File Replication - Backup ?

Jun 5, 2010

I am IT Manager. Currently I am responsible for a mostly IBM shop, running a mix of AIX, OS/400. VMware, and Windows.

My P-series running AIX and Oracle and my AS/400 both back up to tape drives daily.
But my VMware system is not being backed up, the virtual machines are, but my tape drive just broke down.

I just ordered a server grade machine with an i5 CPU, running 3 2TB SATA drives in RAID5, this is going to be my new backup server.

I am hoping I can put Linux on it, and some sort of open source file replications, real time backup software that will back up my Windows servers, and my Windows desktops in real time.... any sort of animal exist?

Debian :: NTFS Backup - Create Ever Expanding (to 320Gb) TAR File That Will Retain All Original File Permissions

Sep 20, 2015

I want to back up an entire Linux system on a 3Tb external Western DIgital USB3 drive.

I do not want to reformat it from what it is, apparemtly NTFS.

Is there a utility that can act like a file manager like mc, that will permit me to create an ever expanding (to 320Gb) TAR file that will retain all the original file permissions. I have had nothing but disappointment with Linux backup utils with a FAT32 external drive, and I am concerned if I just try an tar the entire drive at once, with around 3 million files, I might run out of memory.

Does webilder just keep growing the collection? Or does it ever get rid of old photos? It seems to me an ideal webilder I could set max 100k, it would delete oldest photos to make room for new. Or, like flickrwall (windows), it would just pull one flickr photo per hour, over writing last photo.

Ubuntu :: Growing Raid Crashed Now Can't Get Assembled

Aug 3, 2010

I was growing a 3 disk raid 5 to a 4 disk raid 6.I used mdadm --grow /dev/md0 --level=6 --raid-devices=4 backup- file=/home/user/Desktop/md0.backup for the grow.The drive I added was /dev/sde1. Well it was going strong for like 2-3 days and last time I checked it was at 73% rebuild.Well the frikin power went out on me and when I came back home I can't get the array assembled.

I just have a fear that i lost my superblocks but I'm also a moron when it comes to this stuff.. I would like to think not, but I'm sure there are much smarter people than I on this issue. Any help would help cause of course I have a lot of stuff on my raid with 3 2tb drives.. the irony is I was converting to raid 6 to make sure I had really good safety net.

Red Hat / Fedora :: Growing RAID5 Without Back Up Data?

Feb 15, 2011

I am trying to build a media server for my home and still in the process of evaluating my OS options (Ubuntu Server, Fedora Core, or Win Server). I am planning to use four 1TB drives initially for the RAID5 array. Once it fill up i will add more 1TB drives.

My question is can Fedora Core create a RAID5 array and grow latter without having to back up data to external hard drive and re-create the array? I am looking for something that is easy to use and manage. If Fedora Core doesnt have this option, can you recommend other distributions that can do this?
