How do I set up a regular PostgreSQL database backup in Ubuntu OS?

When you install PostgreSQL, It includes a utility called "pg_dump" that can be used to dump database information into a file for backup purposes.The pg_dump utility is run from the Linux command line. The basic syntax of the command is:pg_dump name_of_database > name_of_backup_file
The command should be run by the superuser most of the time.If you wish to backup a remote system, you can pass the "-h" flag for specifying the remote host, and the "-p" flag to give the remote port.You can also specify a different user using the "-U" option if necessary. The syntax would be:pg_dump -U user_name -h remote_host -p remote_port name_of_database > name_of_backup_file
If you want to backup all of the databases on your system, then pg_dumpall is used.pg_dumpall -U user_name > backup_file
To restore a backup created by pg_dump, you can redirect the file into psql standard input:psql new_database < backup_file
If you want to stop the restoration process immediately when an error is encountered, run the following command:psql --set ON_ERROR_STOP=on new_database < backup_file

Is it possible to create a system image of Ubuntu 14.04 and then using the image in Virtual Box on Win 10?

1) Transferring space between partitionsTo recover space from Ubuntu, I would advice booting with an Ubuntu CD and using GParted to change partition sizes.  You can just add free space from Ubuntu to Windows. Otherwise your Ubuntu files will take as much space inside the VM under Windows 10. I don't see a saving in making it a VM.$ sudo apt-get install gparted$ sudo gparted---------------2) Dumping your Ubuntu and recovering it elsewhere cheaplyBut if you still want to turn your Ubuntu into a VM....You can save a full copy of Ubuntu but you don't need a full disk image to recover your Ubuntu. There is a less space cost that way.And moreover if you transfer a full disk image, unused freespace is part of the disk image and you won't have any savings.In your Ubuntu$  dpkg --get-selections >~/my-packages.txtNow just copy your $HOME directory outside somewhere. You can mount and copy it your windows partition if you have space. For example$ sudo cp -rp /home/my_home /media/backup/my_homeIn your WindowsSetup a fresh new Ubuntu with your favorite VM.   Login as another user or root in your VM. You can utilize recovery boot.Recover your home directory$ sudo cp -rp /media/backup/my_home /home/my_home Then recover your applications$ sudo dpkg --set-selections

How can I backup an Android phone on Ubuntu?

I am answering my own question, as I just found how to get it done. To do this, what you do is use the adb command line. Installing adb can be done either by : Using the Android SDK , or,sudo apt-get install android-tools-adbTo take backup of your device: Connect your phone to the computer.Open a terminal. check that device is connected by running the command 'adb devices'. it should show your device listed. if the listing is there but it has ?????? or similar for the device, then change the usb connection mode. to take a backup you need to run the command 'adb backup' (check other options you may want to use). This will make a backup with the name 'backup.ab' in the same directory where you take the backup.

What is the important folders for Ubuntu backup in my computer partition?

This is one of the reasons that Linux is great. First, you don't have to worry about backing up the operating system. You can reinstall Linux in a matter of an hour and it will be completely up to date with all the patches and needed application.The obvious candidate for backing up things that you have added is the /home directory, but how about a quick list of folders that may contain 'user specific' or 'configuration items' you may care to carry forward to a new installation:/homeEasy one. Everything in this folder are things that you and/or other users of the system have saved. In this folder for each user you will find Documents, Music, Videos, Dropbox, etc specific to each./etcNot necessarily backing up the whole directory, but you will want to grab the 'fstab' file (it contains your filesystem mounts, both local and remote, along with any credentials you have added to mount them)./optThird party applications that you have installed are likely here. Google Chrome, various coding editors, etc. will all install here by default. Since almost everything you install is self contained (and then links to standard libraries installed separately as part of the OS), then if you make a backup, you don't even have to redownload your apps, just copy this folder over./usr/localAgain, this typically contains user created/installed/added content that you may just be able to easily move to your new installation.Hopefully this puts you on the right track!
