Thanks for those suggestions invisible. Yes, making an image before installing a new kernel, version of grub or major update could be a real lifesaver. 

In my quest for the best backup strategies, I've come across several useful websites that list many different ways to backup/restore/clone partitions. I think they could be useful to other members in the forum and I'd like to share them here (I hope that's ok).

https://www.tecmint.com/linux-system-backup-tools/ (extensive list of 25 backup tools and short summary of each)

Have anyone used any of the apps mentioned in these links? If so, which did you find the most reliable and would you recommend to newcomers?

I don't think .dbus is mission critical. It may be one of those config files that is re-created when you log in. I don't have .dbus in my user directory.

Backing up a Peppermint user folder and and restoring to another Peppermint would be fine.
However, if you have decided not to use a certain piece of software in your new installation, then there would be little point in restoring the user configuration files of an unused application. e.g. I always use grsync, so I always restore the .grsync file.

Clonezilla can be used anytime - especially after adding multiple software packages.
Also, it would be advisable to make an image before any major update i.e. new kernel or grub or even adding software from an extraneous source (i.e. an unknown ppa or unfamiliar repository).

I have not used Back in Time so I cannot comment from experience.

Clonezilla and grsync suit my needs and give me confidence to be able to experiment outside my comfort zone.

Hi Slim,

Thank you for your clear explanation on the reasoning behind using symlinks.  :)   It seems like a very elegant solution and how one could avoid problems down the road.  I'm a home user and don't generate massive amounts of data, nor do I have multiple distros sharing the same partition but it makes a lot of sense to me to separate data from the root partition.  This has saved me numerous times since the days of XP.   :D

One thing that still has me a bit puzzled is under what circumstances I could restore my entire home partition.  :-\ From my understanding, in order to restore one's home partition, it would have to be the exact same version of Peppermint (in my case, PM 10 respin) or whatever distro one is using.  However, it seems that one's root partition is much more likely to become unbootable or seriously borked than the home partition getting trashed and that brings to mind, my next question.  If I re-install a sparkling fresh version of PM 10 respin, could I keep using my old home partition or would I need to have cloned the latest "image" of my root partition?

Sorry for all the questions and if I've strayed too far from symlinks but this has got me more than a bit confused.

Thanks again for any suggestions or wisdom that you could pass on.   ;D

Hello invisible and many thanks for your suggestion to use grsync. I can see the advantage of not using compression in order to access individual files and it seems that Deja Dup doesn't save much space when using compression.  I chose Deja Dup initially because I've read good things about it and it's very easy to use.

I connected my WD passport external drive to a different usb port today and was able to make a backup but got the following msg after verification of files at the very end: "could not backup the following files: /home/alan/.dbus and make sure you are able to open them." Are these files "mission critical" to restoring a backup?

I'm still not clear about restoring the entire home partition. Would it work on the same version of Peppermint or is this asking for trouble and would mess up a clean installation?  Should I just restore everything in my home folder from the home partition? In that case, it doesn't seem necessary to backup the entire home partition... I've been in the habit of separating my data from the system since the days of XP and it's saved me and my data more than once but I really don't have experience of restoring an image. I usually end up just reinstalling the system if things get too messed up but this isn't the most elegant way to do things. lol!

As far as using Clonezilla for making an image of your system goes, is it best to use it immediately after installing one's desired distro and all apps or can it be used at any time to take "snapshots" of the system? Maybe "back in time" would be more suited for this purpose?

It'd be great to hear any thoughts and suggestions on these topics. :-)

Hi Sgt_Pepper,

I'm very happy to read your appreciation of the tutorial. Thank you very much for the kind words!  :)

While there is no really best way to set up your partitions, the way I describe in the tutorial is very good and has stood the test of time. The main improvement that one might consider making (as a private home user -- web server users or users with large data base applications usually have different requirements that this tutorial was not intended to solve) is to create a separate /home partition and then put the symlinks to the data partition files in that /home partition. The /home partition is primarily then your repository for the configuration files for most programs and can be backed up itself -- but I advise strongly that you do not use these configuration files (i.e. this /home partition) with any other linux distros or even any other versions of PeppermintOS. The reason is that different distros and even different versions of the same distro can use different program versions that frequently have different configuration files or different config file syntax. This can and has resulted in sometimes very difficult to solve issues. Therefore, other linux distros or other versions of PeppermintOS should get and use their own /home partition.

Regards,

-- Slim

It is also very considerate to mark your issue as (SOLVED) by going to the initial message, clicking on the button Modify, then  adding (SOLVED) to the Subject: line of that message and finally saving/posting that change.  ;)

If you share your fix, other forum members with the same problem may benefit from your knowledge.

grsync for backing up data.  The main advantage is that you can then access individual files or folders because there is no compression. The first backup may take a little time, but subsequent backups are incremental and pretty quick.

I would not restore a complete home backup to another Linux system because of conflict of configuration files.
However, I would restore data folders (i.e. Music, Documents etc)

Clonezilla is perfect for creating an image of your system. It does need caution and a bit of practice to become confident in its use.

Well, this is pretty sad but I'm reply to my own thread. ;-)  I tried to make another backup on Deja Dup this evening but it failed.  It seemed to start without a problem and scan files for changes but then abruptly stopped after about five minutes and I got the following message: error creating directory /media/My Passport: Permission denied.

I'm using a WD passport 2TB external drive and have a directory there from the previous backups. I don't schedule weekly backups, nor do I leave the external drive connected all the time.  I do backups when I choose and the external drive was mounted and the backup process seemed to start alright.  Another strange thing is that my WD external drive has disappeared from the file system even though I believe it's still mounted and the light from it is flashing.  I don't know if the usb port is defective or somehow the previous backup got corrupted.  I've tried a few more times to start a new backup but keep getting the same msg as before (error creating directory /media/My Passport: Permission denied).  I'll disconnect it after shutting down my system and check the drive on another usb port tomorrow.

I'd really appreciate any ideas or suggestions someone might have.
