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)?
Several months back I backed up a windows hard drive using an ubuntu live cd and this commanddd if=/dev/hdx | gzip > /path/to/image.gzI now want to restore that image but so far have not been successfulI have tried to restore using this commandsudo dd if=/path/to/file.gz of=/dev/sdb1After some time has passed, the terminal reads23568129+1 records in23568129+1 records out12066882348 bytes (12 GB) copied, 1327.65 s, 9.1 MB/sIf I reboot to windows with the 2nd hard drive connected as a slave. I go to my computer to try and browse the files of the restored HD but when I double click the drive, windows saysthe disk is not formatted.I have also tried sudo dd if=/path/to/file.gz of=/dev/sdbAnd when I do this, the disk does not show up in places/my computer but it will show up in gparted and Disk Management
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.
im trying to clone my ubuntu system installed in a laptop in case the laptop crashes.
But, first of all: when i try to restore the system in a new PC, could be incompatibilities because the hardware of the broken laptop and the new laptop is different?
I dont mind if i have to buy another laptop with the same processor type (i386, etc), but, for example, the type of the RAM could be cause of problems?
I want to restore a HDD image I have to my laptop's HDD while booted off the Ubuntu Live CD.The laptop's HDD is unformatted and has no partitions.I expected this to work:$ sudo dd if=/path/to/backup.img of=/dev/sdaBut I'm tolddd: opening `/dev/sda': Permission denied.
Before I reinstalled Ubuntu (this time allocating the entire disk to it as I never really used Windows any more) I backed up the entire contents of my /home folder using Deja Dup. Now that I am done reinstalling Ubuntu I am trying to restore the backup. However, when it actually begins restoring the backup, it says "Restore failed: failed with an unknown error".
I've been using 11.04 Unity, & quite like it. I fired up Blender 2.49b the other day (not used it for a long time) & its behaviour was very erratic. Due to this I decided to reinstall 10.10 for the time being, until October or maybe even the 12.04 LTS. I backed everything up & reinstalled 10.10. I then tried to restore my Evolution from the Natty backup file, which simply didn't work. The message was something about it not being a valid file. I'm assuming this is a non backwards compatibility issue.
Any way getting Blender to work or restoring Evolution? With regard to Blender (in Natty); I've not tried proprietary drivers for my GPU yet as the open source defaults have always been fine, so that's an option. It means another reinstall (of Natty), but that really isn't such a big deal at this point. With regard to Evolution (in Maverick); I found a ppa but I'm unsure how to proceed once I've added it. Would I do an apt-get update & an apt-get install evolution?
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.
I have a samba share to a windows 7 computer I do not know if I will be able to use backintime or not so I want to know how to have rsync do my backup.I read the man but I'm not sure if I understand the it.on same computer different hard drive to run every hour in a script. Leanne is windows 7 share and backup is the other hard drive in the computer rsync -arvRzEP /media/leanne /media/backup.
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.
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'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.
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'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'd like to backup my whole system to a 2nd disk using rsync (other tools not possible).Which paths should I exclude from the packup?I was thinking about /proc, /dev, the lost+found directories...What other paths am I forgetting?
I'm syncing a server over the internet with rsync, but it only works for a few hours before the backup fails with a "No route to host". I can restart the job and it'll will pick up where it left off, but is there an automated way to do this, or protect against a connection failure? I have about 170GB to copy over initially, but I can only get through about 4-5GB before the connection drops--manually restarting the sync everytime it drops will make the initial backup take days...
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).
well, i know ther are issues when using rsync to copy files to ntfs partition like file permission blah blah. the thing is, i need to backup my music files periodically onto a ntfs partition from ext4. i really dont care about file permissions or any other stuff. when i use rsync, it should update the mp3 files on my ntfs (external) disc with the new ones.can i give a go with this operation? i have lot more important files on the external disc and i dont want this rsync corrupt or delete those files coz they are highly important files.
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'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?
