Ubuntu :: Permissions With Rsync On Backup
Jun 18, 2010
I'm trying to learn how rsync works to backup my system. I tried:
Code:
rsync -azvv /home /media/Elements
I get a folder called home on my external hard drive but when I use ls -l to see the permissions they are all wrong.
On my /home folder the permissions for /nathan are
drwxr-xr-x 48 nathan nathan
The permissions on the backup /nathan folder are
drwx------ 1 nathan nathan
I also tried using the long version of -a which is -rlptgoD and that didn't work either. What do the 48 and 1 mean when I used ls -l? When I look in the /nathan folder the permissions are all screwed up too. A lot of the files are backed up as executable and the permissions are all screwed up. I also ran it with sudo, and that didn't work either. The permissions were still screwed up and ownership is messed up too.

I wrote a script to wake up my windows machine and do an rsync backup of some of my files. I wanted to make this command a accessible through local bin so I made it executable. However the problem is that when I copies files is copies them with root permissions and i can edit or delete them. How can I set the files so they transfer with the proper permissions for my Ubuntu user?
Code:
#!/bin/bash
# Description: This script first wakes up the client machine and syncs the appropriate folders.
# Finally the script shuts down the client if it was off to begin with.
if [ "$(whoami)" != "root" ]; then
echo "Permission Denied"
exit 1
fi .....

Problem: permissions for rsync and BackinTime. Setup: Ubuntu 11.04, Two internal HD, #1=main, single boot, #2=backup drive. Question: How do I set up my 2nd HD with correct permissions? Background: I had previously a dual boot XP+10.04 with a 2nd HD formatted as NTFS. With this I was able to use my rsync and backintime to my 2nd HD with no issue. My new set up is EXT4 on both HD.
(I even tried to reformat my 2nd HD as NTFS, but that didnt fix the issue) I followed [URL] to mount the 2nd HD and get permissions. But now when I run backintime i get this error: [E] Error: rsync: opendir "/home/myhome/.ssh" failed: Permission denied (13) I did my requisite reading for a newbie, and am stuck. I ran backintime as root, and it backed up ok. How do I run my user version of backintime? (i.e. How do I fix the permission issue?)

I saw in a magazine reference to using rsync to have identical copies of folders. This looks like something I could find useful as I have a large number of items in need of safe backup.
I have the folders on an old system on a home network and would like to copy these over to a USB Hard Drive.
Currently the folders reside on SFTP xxx.xxx.xxx.xxx and I wish to sync them to a USB port on my laptop.

This should be a quick one. I'm trying to backup a single directory and it's subdirectories on my Lucid Server to a freenas box across my network. This is what I'm using to do that rsync -r -a -v -z * --delete freenas: DSIBackups..It almost works perfectly except for one problem. When a file is deleted at the source, this command doesn't seem to delete it on the receiving end. I assumed that the --delete would do that but aparently not.

when rsync is finished the update, or in the meantime - i need to move the updated files to a different location - like date +%Y%m%d something or what ..the reason is, because of the development, i need the modified files, but all of them, not just the last one - so i have to store them daily, but i dont want to store the whole dir - just that few files which are updated does it make sense?

I'm hoping somebody can find something here that I haven't. I'm trying to use rsync to backup home directories to a nas. First, I NFS mounted the nas and ran an rsync and everything worked out fine. the transfer completed after a few hours and everyting was transferred (lots of stuff!). I then decided that I don't want to leave the nas mounted all the time and I didn't want to automate mounting and unmounting of the nas as I didn't think I could produce a script that would work reliably enough. So I decided to start an rsync daemon on the nas and upgrade via that. I run the following command (results are included. the ^C is me killing it after it hangs).
Code:
ryan@server:/etc/backup$ sudo rsync -ax --stats --progress --delete /data root@192.168.0.98:backups1
root@192.168.0.98's password:
sending incremental file list
data/home/user/Documents/
data/home/user/Documents/The File.wmv

I have a Linux host acting as an ISCSI server for a Windows box. I want to keep an off site backup, so I figure rsync will keep the ISCSI server synced with an offsite Linux host. I understand that Rsync does block level incremental transfer to conserve bandwidth ok, awesome.The trick is, that I also want an archival copy kept. Say I want to go back to a revision of a file from 10 days ago, I need to be able to do that.
I was planning on using Backup Exec, since we currently have a licensed copy. Throw the archives from Backup Exec onto the ISCSI server as well, and have it keep a rotating 30 day backup, or something like that. The issue I see here is that this will be creating a deleting files as it does its daily backup rotation. I'm guessing RSYNC will see these as new files, and likely retransmit everything on a daily basis. The question then becomes, is this assumption correct, or will it still know to do a block level incremental transfer even when file names and such are changing?

Our backup script was working fine (ssh to the server, back up /home to a second hard drive on my computer). Then right after an ubuntu update, it quit working. I investigated and found that "something" had changed the label on the backup hdd to what looked like gibberish to me. But the script identified the backup hdd by its uuid, which didn't change. Yet, here is the error I get when the backup fails: receiving file list ... done [took about 5 seconds] rsync: mkdir "/media/14D9-3B1F/server-backup" failed: No such file or directory (2) rsync error: error in file IO (code 11) at main.c(594) [receiver=3.0.6]
Note that the backup hdd IS mounted, uuid is correct, and the folder 'server-backup' DOES exist. Does anyone have a clue for me? I'm moderately experienced in Linux and ubuntu. Our server runs centos 5. And as stated, the backup ran fine for several weeks. I think there was a new linux kernel on that update, but at this point a while later I don't know which one. Current kernel is .2.6.31-22-generic.

I support a small business which has an Ubuntu server running as a file server. The server is running Ubuntu 10.4. There is one hard drive which is mounted as /media/hdd. Each night this is backed up to an external USB hard drive mounted as /media/backup. The backup is carried out using the command:
Code:
rsync -av /media/hdd/ /media/backup/
Is there a way to encrypt this back-up so that if the USB hard drive is plugged into another machine it cannot be read?

I know rsync generates a lot of questions, but I have not found an answer to this one about whether the archive option (rsync -a) ever misbehaves. I am transferring data from field instruments running Debian etch to a central server running Debian lenny. My command is below:
Code:
rsync -av --remove-source-files --log-file=rsync_20110612_0656Z.log ./20100616/ archive@bigserver:/mnt/ZAP_DATA/20100616/zap2/
After rsync runs, the directories it touches on bigserver have very strange permissions
as follows:
Code:
d-wxrw--wt 2 root root 4.0K 2010-10-26 04:31 20101026
This says that directory 20100226 can be written by anybody, but can't even be read by its owner! I thought rsync was messing things up, but in the process of writing this question I discovered that the original files that I am trying to sync have these crazy permissions. So I no longer have a question, but if future LQers think that rsync -a is messing up their permissions, this post may confirm that it is merely copying their messed up permissions from somewhere else, as it is supposed to do!

I try to use rsync for backing up some directories and I have to following problem: some files have permissions that prevent me from running rsync under my own user id. So I run it under root using the option "-a" which according to the man page should preserve the permissions, owner and group information:
However, when I run this under root, the directories created in the backup location get user root and group root while ordinary files keep the original user and group. What am I missing here? How can I get rsync to preserve the user and groups for all files, including directories?
Here is a command to illustrate my problem
Code:
sudo rsync -a /home/youruser /tmp
If you try that and terminate with Ctrl-C after a few seconds, there will be a directory /tmp/youruser where the directories contained within are owned by root group root.

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 want to save a backup of my data on a remote server, but never want the backup server to see the data unencrypted. Editing a single file and backing up should not result in everything being encrypted and sent again. The remote server should preferably not even know the directory structure (and especially not the directory names).

I've been trying to make a three stage backup with stage 0 being a full monthly back up, stage 1 being a weekly backup, and stage 2 being a daily backup. I've been trying very hard to use rsync for this but sorting files by date is proving to be problematic. Sometimes it seems to work from the command line directly, but the same command causes errors and warnings from a script while entirely failing to sort the correct files.
The common example I see for this involves commands like this:
Code:
rsync -Rav `find /home/ -ctime -7 -print` /path/to/home_backup The problem seems to be that since the user directories in /home contain files that have been altered within the time frame specified the whole directory is matched first which means that the whole directory is recursively archived as opposed to just the changed files.
I've also seen examples using the --files-from tag using the same find parameters and this one seems to ALMOST work but gives me strange warnings and fails to run at all when launched from a script.
Many of the things I've googled about using rsync to backup stuff by the date modified involves a rather snarky "You're missing the point of rsync!" to which I respond by yelling at my computer monitor followed by "JUST TELL ME WHAT I NEED TO KNOW!" I understand that rsync is meant to take care of incremental backups on it's own, that's why I want to use it specifically for a traditional 3 stage backup scheme.

To copy from production to standby over the internet I use a cron job doing rsync -avze 'ssh -p 8022' --exclude-from= ....
My question is: should the cron job run on the production or the standby system. Root access to the remote system is given by a pass phrase-less ssh key. Currently I run rsync on the production system. I guess that it is more secure because the standby needs no ssh login to production. Running rsync on the standby would use less resources on production. I am concerned that in this case there would be pass phrase-less access from standby to production.

I'm doing an rsync backup to an external drive in order to take a shot at setting up partition encryption. My rsync command is, as root: Code: rsync -av / /external1/backup.Once I've finished my cryptsetup and done a fresh Linux install, what command should I use to properly restore my backup (without messing up the encryption setup)?

I'm going to make a nightly backup copy from one server to another, using rsync. If I have a sufficiently large file, say 4+ GB or so, I'm not interested in copying the whole file if only a small change has been made. Can rsync detect small changes on block level and backup only those if needed?

I want to backup windows PC's in my network to my ubuntu 11.04 pc, using rsync. Rsync is working, but I have to mount the pc's. A few details.
My server is named: server
The windows pc is named: \PC_OF_MARTIJN
The folder where the mount is coming is: /home/bastiaan/backup/mounts
Credentials are in /home/bastiaan/backup/credentials and they're called: martijn
So what I'm going to add to /etc/fstab is this:
Code:
//server \PC_OF_USER /home/bastiaan/backup/mounts/user cifs credentials=/home/bastiaan/credentials/user,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0
Will this work?

am trying to sync data from Server A to Server B. The destination on Server B is a CIFS share and I need to preserve timestamps, permissions, etc. on all the data that I transfer. During the rsync process, I receive thousands of errors like the one below:
rsync: chown "/LBDCASAN001/JasonHarper/files/1259810304676/2010-12-22-01-00-03/0x22/0xc8/0x43/0x0a" failed: Permission denied (13)
I'm not sure if it's related at all, but my mount point on Server B has the permissions set as: drwxr-xr-x 2 root root when it is unmounted. When I mount the CIFS share, the mount point permissions change to: drwxrws---+ 3 root root
Also, here is the line from my /etc/fstab that mounts the share:
//X.X.X.X/LBXXXXX001 /LBXXXXX001 cifs username=LBXXXXX001,password=XXXXXXX!,uid=0,gid=0 0 0
When I perform the rsync, I'm authenticating to Server B from Server A as root.

I am using Rsync to backup files to a another machine, the users on my fileserver do not exist on the backup server so Rsync throws errors about the permissions. It copies the files fine but I want to get rid of the errors and have Rsync ignore the permissions when backing up.
/backup is a mounted ftp directory
Below is the current command and output:
Code:

When I backup to a local directory the permissions are copied correctly.

I've got an older RHEL 5.5 server that we're using for our company email server. We're going to retire this server and I've created a new Debian Linux server as it's replacement. Now I'm trying to rsync all the users /home/ directories to the new server however when I tested this, I noticed a problem. In the old source server where I'm running the actual rsync command from, everyone's home directory is owned by their unique UID and a generic GID (100 = users). So when I execute this command on the old RHEL 5.5 server:
Code:
rsync -e ssh -avz /home/* root@192.168.0.101:/home
Why are all the users home directories being owned by root:root on the target server? It's not owned by root:root on RHEL 5.5 and the only thing I can think of is my rsync command is wrong. According to the man page, I can see that using the -a switch should preserve all file ownership and much more. It's not doing this on the target Debian server. If it tries to copy over /home/bob and it's owned by bob:users, if Debian didn't know or have a UID for Bob, wouldn't it just assign a UID from RHEL 5.5 to the Debian server? So like /hone/bob would be owned by 1009:users?
