How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
sfdiskfrom theutil-linuxpackage. For whole-disk non-incremental backup you can usedd. I am not sure how to deal with whole-disk incremental backups and LVM dump/restore. If you backup withddyou don't need to worry about restoring the LVM. As a casual desktop user I only back up my data. It is simple, faster, and requires less storage. However in the event of a crash, it will take me a few hours to restore my system. I would only consider whole-disk backups on a server where I cannot afford a long downtime in the event of a crash.sudo sfdisk -d /dev/sda > part_sdato make a backup of the partition table. I hope that's good enough.sudo pvdisplay. They would help to recreate the LVM if required. With a backintime backup you can definitely restore all your data. If you want to be sure that you can also restore the whole system you could test the procedure with a virtual machine.
