Cobian Backup 11

[Billie Kjergaard]

CobianBackup is a file-backup program that can be used to make automatic backups for your directories and files. Cobian Backup can be run as a service or as a regular application. It can backup to some other location in the same computer, to the network and even to an FTP server. The program supports compression and encryption.

Cobian Backup was originally released in 2000. The program was later rewritten and released under version 7.The next version (version 8) was released in 2006. Its source code was later released under the Mozilla Public License in late January 2007. However, with version 9 the author of Cobian Backup decided to switch back to a completely closed source model.[2] Older versions will remain Open Source forever, as the release of the program under the Mozilla Public License cannot be revoked.

Cobian Backup supports Unicode,[4] FTP,[6] compression (ZIP, SQX, 7z), encryption (including Blowfish, Rijndael, DES, RSA-Rijndael [1]), incremental and differential backup, for example a differential backup every night (which backs up user files that have changed since the last full backup) and a full backup every seventh night (backing up a full set of user files). Backups can be saved to CD, DVD,[6] USB memory stick, a second hard drive (internal or external), etc. It supports long file names (32,000 characters) for all backup routines.

I have Cobian installed as a service on two Windows machines: WinXP SP3 and Win7 x64. On both machines, the service is set to log on with my user account which is in the Windows administrator group. Backups on both machines fail with the message "Couldn't create the destination directory "\\nas1\backups\foo\bar\": The filename, directory name, or volume label syntax is incorrect".

If you are using a cloud storage device, like WD Cloud, instead of a domain related server, all you have to do is make sure to match the SAME username AND password on both systems. That is, create a LOCAL user, like "BackupUser" with a password, set that as the login user for the Cobian service, then go to the cloud device and configure the SAME username and password there as well when securing your cloud shared folder. This allows Cobian to run as a Windows service, which is better because a local user doesn't need to be logged in to keep your machine backed up.

Launch Services on Windows , open properties of Cobian Service , under Log on tab , Change it from "Local system account" To an account which has network access (example: the Administrator account or your own personal account) .Look at : _vs_service.html

I resolved it by right clicking on the task, then Edit task, Advanced, Run the task with another user. Then I put username, domain, and password again, my Cobian started with this error when I changed the user password, before that it was ok.

I have a client that we aree trying to move from On-Prem backup of their files to Cloud storage on Wasabi. Cureently they are using Cobian Backup 11 and I understand that he sold the Source Code a few years ago. Interestingly we have not been able to find what the purchaser did with it as searches for v12 do not yeild something we can download and test.

Given the pandemic forcing some of their people to work from home, we have agreed that Wasabi or (similar) may be a more effective storage option. That being said, I have been looking around for a client that can work with Wasabi while being as goof-proof as Cobian without as many errors. We would also really like to have email notifications of each backup (success, failed, paused, etc) and scheduled automated action is a must. If we can also customize it that would be a plus.

In honesty, Mr. Cobian really did a good job of developing a simple effective product with a clean no-frills UI. It was not perfect but it did make the attempt to goof proof a task that nobody likes to do and so many take for granted until crisis hits. Since he sold it, there is confusion as to what has become of it. Although Cobian Backup 12 appears in searches, they do not lead to anything. Has anyone ever found what Mr. Sweeny did with it or been able to download Cobian Backup 12?

i was wondering if there is a newer product than cobian backup that support backup as a service, schedulation, send log via email, windows server os and the removal of older backup. of course it must be a free product like cobian.

the os is windows server 2008 r2 and the nas is a synology ds414 with 4x1 TB wd red, regarding the cloud backup solution is not achievable because they have just 0.70mbit of bandwidth in upload and the size of the backup are too large

I have been following backup solutions for many years and this seems to do what I need. I currently use Cobian on W10. I am considering changing my Windows email from LiveMail (which has not been supported for a long time but can still be downloaded if you search hard enough) to Thunderbird but, unlike Livemail, which backs up each email message into a separate file, Thunderbird seems to place all of its emails into a single mailstore file.

As I schedule a backup daily to NAS storage backing up a single mailstore file daily will take up a lot of space I currently take a full backup every 28 days and keep three full backups and the incremental changes between.

I am also concerned about the fact that Duplicati is still in beta although it has been in development for several years. If there had been a stable version I would probably have changed to it long time ago.

Thank you - I think I will have to take the plunge and try our Duplicati. As a now retired system architect for many years I like the concept but my programming skills are quite rusty now. I was the leader of a multi-user OS team in the around 1975 1970s. As an aside we supported 70 concurrent text mode users on a Modular one (UK computer) and the memory limit was 256 kilobytes and the largest disk we had was 50 Mbytes!

My background makes me cautious to an extent and I tend to avoid beta software and experimental versions unless I am very close to the development team. If I were not contemplating migrating to Thunderbird I would stick with Cobian which has served me very well for very many years.

demonstrates what I mean. That value is a hexadecimal display of flags, and by deleting a message in a local mailbox I changed it from 0001 to 0009, basically setting the MSG_FLAG_EXPUNGED flag in-place.

I am considering changing my Windows email from LiveMail (which has not been supported for a long time but can still be downloaded if you search hard enough) to Thunderbird but, unlike Livemail, which backs up each email message into a separate file, Thunderbird seems to place all of its emails into a single mailstore file.

You can configure Thunderbird to store each email message in a separate file. See Maildir in Thunderbird Thunderbird Help

Also, unless I forgot that I changed it?, but my Gmail imap account in Thunderbird uses maildir.

Is there a simple step by step guide to get Duplicati to run as a service but with the backup scheduled to run every day? I am sure it is simple once I have worked out (and documented) how to do it but it would be even better if one already existed.

Some of my questions are based on my membership of a local computer club where I maintain a support site where tried and tested software is published. I provide technical guidance to our members on useful and reliable software. Backup is coming up on our agenda quite soon.

One question that crops up regularly however is can I initiate a backup job automatically when I insert a specific USB external drive. Some commercial software can do this but I am not aware of any Open Source projects that do. I personally have a NAS that is permanently available.

Since you only want to have your partition synched, I recommend to use the incremental option, but also having the "create separated backup using timestamps" option turned OFF. That is found under the task properties, in "general". That way, you will only copy new and modified files without having to deal with different versions or separated backups.

Also, even if you already have some of the files in the target partition, the first time Cobian makes a backup, by default it will try to make a FULL backup (despite setting it to incremental) and it will in fact overwrite files because it being the "first time" backup. To avoid that, go to Options > Engine, and be sure to turn off "First backup always full". That is always recommended if you are just "updating" a previous backup made from just copying files manually.

Another thing, if you manually copy files after a backup to the new partition, and you don't want to "waste time" copying (in fact overwriting) them because Cobian thinks they've been copied from the source, be sure to turn off the "use file attribute logic" option OFF, under General options in the task properties. That is because by default, Cobian "knows" that a file is backed up by an attribute called "archived", and not by seeing the file itself already there. Since you only want to copy new and updated files, and you probably already have some files there, turning off that option means that it will not re-copy files that are already there (unless they are newer).

Since you are not creating separated backups, every time you backup, you will only have ONE backup version of everything, besides you will not have additional folders with several dates and versions of some files, which is what you want. That is, you will have a copy of the same files and folders structure from your source partition.

With that settings, the backup will actually only make a copy of new and modified files from the source partition into the target partition, but it will NOT delete files from the target partition if you delete them from the source one.
