My church is planning to purchase a NAS serving 9 PCs running Windows and Linux respectively. The new device apart from storing data, mainly photo, is expected to be used for backup keeping all PCs images.
I have been googling a while unable to find a solution running dd command over LAN.
I launch a mdadm grow to expand my filesystem but I forget --backup-file.I have my server running and one UPS.
Code: Select allpk25.com:~# mdadm --manage /dev/md0 --add /dev/sde1
mdadm: added /dev/sde1
pk25.com:~# mdadm --grow --raid-devices=5 /dev/md0
mdadm: Need to backup 3072K of critical section..
pk25.com:~# mdadm --grow --raid-devices=5 --backup-file=/root/md0-grow.bak /dev/md0
mdadm: /dev/md0 is performing resync/recovery and cannot be reshaped

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
I am now preparing myself to upgrade lenny to squeeze and decided to do a backup on my system. I used backup-manager to do the job and it worked fine. how do you restore said backup data?

I want to have a full backup of my HDD ,incase the hdd fails in laptop i can mirror it to a new hdd from the external hdd.
Sadly I am unable to login to a particular user via the GUI, but that is another thread [URL].
I know that you can create a single backup file of all your emails and settings when you have access to the GUI in Evolution. Since I am unable to login to gnome (or KDE) but I am able to login to the command line by su to the user I would like to create a that evolution backup file. I will be reinstalling Ubuntu.
I'm going to be using this command to back up my files:
Should I change anything or is it ok?
I'm new to Linux and I am currently using the Ubuntu distro. What I'd like to know is whether there is a program or command I can use to back up my hard drive with Ubuntu? I have an external drive that I can use for this purpose but I don't know how to set it up for Ubuntu or Linux generally.

View 1 Replies View RelatedI back up all my digital photos to a couple of places. I've been using the cp command, but--given the personal value--have started to wonder if there's a more reliable way. I'm no stranger to Linux, Bash, Perl, etc., so I could write something to copy and compare md5 hashes, but I was wondering if something already exists (reinvention, wheels and what-not).
Most of my googling for copy and (verify|valid|check|hash|confirm) turns up rsync. However, as far as I can tell, rsync only uses hashes to see if a file needs to be updated. It doesn't perform a hash comparison afterward. For this use, specifically, the files are binary and typically 8-10MB.
I have 2 'how-to's' with rsync neither are working. I need to backup nightly some items and using a command line, I am prompted with a password, enter and it works. I now tried these 2 items in the shell script, both of them still when run prompt for a password. I have tried;
#!/bin/bash
export RSYNC_PASSWORD=passwordhere
- and -
also created a blank file called pw (to test) and then tried
#!/bin/bash
rsync --password-file=/pw xxxx
Both of those options when run still prompt for a password. These severs are running old RH9 servers.
Does the dump command back up entire file-systems or is it capable of backing up subsets of a file-system? And is tar capable of taking device names (for file systems) as input to be archived?

I'm trying to backup a whole startup disk to another with GRSYNC but I don't need some files or directories. For example, I don't want to backup my 'swapfile1' (I do not have a dedicated swap partition) or the 'media' directory' in order to no enter a looping sync.I've searched the web for the correct syntax of the --exclude command but none have worked if applied in the advanced option "before" rsync starts. These a sample of NOT workin syntaxes:
exclude /media or -- exclude 'media' or -- exclude "media"
same for swapfile1:
exclude swapfile1 or -- exclude 'swapfile1' or -- exclude "swapfile1"

View 6 Replies View RelatedI'm in a directory containing various files and subdirectories, one of which is called BACKUP and is initially empty, what exactly happens if I launch the following command line:
Code: cp -R . BACKUP???
If I'm not mistaken, all the content of the current directory should be copied into the BACKUP directory, apart from the directory BACKUP itself. Actually I get a message saying something like:
Code: cannot copy a directory onto itself BUT when I look into the BACKUP directory I find another directory called BACKUP which I did not expect to find. Moreover, if I launch the same command again I get the same message (repeated two or more times) and then I find that inside the "second" BACKUP directory there is a third one, with the same name again. In other words, every time I launch the command I get a deeper tree of "BACKUP" directories, as if the command was messing everything up. I know that most probably I'm the one who's messing things up and I also know the "problem" can be easily bypassed by using as a destination for the copy a directory located elsewhere, but I'd like anyway to understand the reason for such a behaviour.
I am fairly new to scripting and I am trying to write a script that finds and zips a file named file1.xml from multiple sub-directories. So basically I want to find them and zip them all together. The disk directory structure is as follows:
/mnt/data/user_name1/db/file1.xml
/mnt/data/user_name2/db/file1.xml
(etc, etc where user_name varies)
This is what I have so far, but I keep getting an error relating to the -name command.
filename=`date +%d%m%Y-%H:%M`
find /mnt/data/ -name file1.xml -maxdepth 2 -type d | zip -rp $filename.zip -@
I keep getting the following error but don't know how to fix it. Is what I am trying to do even possible?find: warning: you have specified the -maxdepth option after a non-option argument -name, but options are not positional (-maxdepth affects tests specified before it as well as those specified after it).

all my test restores in vbox worked fine. i may use the backup as a second OS, so it works. but there i first deleted the old OS and than ran cp -a /media/backup_partition /media/restore_parititon.
yesterday i ran into trouble and had to restore my system.
mount /dev/sda1 /media/restore
mount /dev/sdb1 /media/backup
rsync -auv /media/backup/ /media/restore
that did work, but not so good. dpkg-errors, all non-repo-apps, like opera and some old thrash, were a mess. i had to reinstall them with dpkg to delete them. besides that the system is up and running, but it was a lot of work.
I would like to backup my wicd profiles. I thought it would be sufficent to copy /opt/wicd/data and /opt/wicd/encryption - however, those path do not exist in lenny (which I am running). So which path / folders / files do I need to backup in order to back up the wicd profiles and configuration?

View 10 Replies View RelatedI have been a windows user for a very very long time, and recently switched to debian. I have so to speak crapped all over my system failing to compile sourcecode properly held broken repos and what not.
So decided to reinstall debian last night, now I have a rather clean fresh installed copy. As I'm a new user to linux, I want to setup a backup system so I can revert to a clean fresh installation when I muck up my system.
Now I have downloaded and installed BackupPC with needed libraries and sitting here trying to configure it on my computer. I have followed this guide: [URL] ....
I have come to this section here:

********************************************************************
Now I'm not quite sure what to do here as I have no networked computers to deploy to only one machine. Although I want to make a local system backup and upload that to a server I have access to, but would that server be seen as a backuppc server/client?
On this computer here I have generated the id_rsa and id_rsa.pub located in /var/lib/backuppc/.ssh
looking at this part:
Test ssh connection(On server, as Linux user backuppc)
backuppc@server$ ssh root@<client machine>
How should I interpret @<client machine> should that to be ssh root@127.0.0.1 ?
I switched last summer from Windows (used it since Windows 95) to Debian. I'm using Debian Jessie for a couple of months now and I'm getting used a little.
There are problems here and there, but I can solved them with some reading on the web. Not really a big problem...till now
I run Debian 8.2 om my PC (PC1). Bought an older PC (PC2) that I want to use as a backup server.
I'm using PC2 only for making backups, after the backup I switch it off again.
So I installed Debian 8.2 (net-install without DE and with SSH) on PC2 and tried to configure it to let it work as my backup location. Made a public SSH key and exported it to the root account (no problem) and to the user account (sensdeb), but there was an error "Access Denied"
Gave the user (sensdeb) sudo-rights via visudo file
# User privilege specification
root ALL=(ALL:ALL) ALL
sensdeb ALL=(ALL:ALL) ALL
I installed rsync.
The problem is that Rsync only works when I use the root account.
Code: Select allrsync -r -n -t -v --progress --delete -u -l -H -s /media/Data/Mp3/Anastacia root@192.168.1.102:/test/Mp3
When I try to sync with he normal user account sensdeb
Code: Select allrsync -r -n -t -v --progress --delete -u -l -H -s /media/Data/Mp3/Anastacia sensdeb@192.168.1.102:/test/Mp3
I get error's. Access Denied
I don know how to give the user sensdeb the rights so that I can use that account for my backup tasks. Now it's possible to sync with the root account, but that should not be the way to do it, I read many times.
I am going to use 'rsnapshot' to create backups of my local & remote computers. My intension is that I can use these backups to restore disk images when needed -> install Linux from scratch and then copy the subdirectories from 'rsnapshot' backup to the new Linux installation.My question is what subdirectories should be excluded in the backup.

using Back In Time to backup my home directory to a second hdd that is mounted at /media/backupThe trouble is, I can do this using Back In Time (Root), but not using Back In Time without the root option. This is definitely a permissions issue - it can't write to the folder, but when I checked by right clicking on the backup directory and looking at the permission tab, it said I was the owner

It also measures time needed to complete it and deletes archive older than XX days (set in find -mtime +20) and makes incremental backup every weekday and FULL on Sundays (which suits me bcoz no heavy load).
Files for TAR to include and exclude are in txt files listed each line separate name:
