Back In Time: Ubuntu backup tool |
vote
|
|
Back In Time is a simple backup tool for Linux inspired from "flyback project" and "TimeVault".The backup is done by taking snapshots of a specified set of directories.Keep in mind that Back In Time is just a GUI. The real magic is done by rsync (take snapshots and restore), diff (check if somethind changed) and cp (make hardlinks).
Back In Time acts as a "user mode" backup system. This means that you can backup/restore only folders you have write access to (actually you can backup read-only folders, but you can’t restore them). read more... |

Scripting: A parallel Linux backup script |
vote
|
|
This example bash shell script demonstrates a simple method of creating backups of multiple filesystems to multiple tape devices simultaneously. While the script presented writes to four tape drives in parallel, it can easily be modified to write to other device types and to create a different number of backup streams. The script is set up for the bash shell under Linux, but modifying it for another variety of Unix should simply be a matter of changing the locations of utility files such as tar, echo, cp, and sleep.
The script can be downloaded from http://librenix.com/scripts/par.tar.sh. Download the file now and load it into an editor as this article will refer to it frequently. Also, you may want to modify bits of it to match your filesystem names and your devices.
The first line of the script looks like this:
#!/bin/bash If the bash shell isn’t in the /bin directory on your system, you’ll need to modify this line. Enter the command which bash now to verify the location of bash. My Fedora Linux system and my Mac OS X system both have bash in /bin, but my FreeBSD system does not. If you have a non-Linux flavor of Unix, you’ll probably need to use the ‘which’ command to verify the locations of each command used in the script. The commands used are:
bash
cd
sleep
echo
date
tar
wait
ls
wc Note that ‘wait’ and ‘cd’ are usually implemented as internal shell commands and may not have external commands associated with them. If that is true for your system, leave ‘cd’ and ‘wait’ with no directory prefix just as they are in the original script.
Now, the first command in the script resets the current working directory to ‘/’:
cd / Since the script precedes each directory to be backed up with a ‘.’ to represent the current working directory, starting out at ‘/’ is necessary. The reason for this precaution is that some implementations of the tar command will only load files from a tar archive into the exact directory that was specified when the file was backed up. By prefixing the names with a ‘.’ we preserve the ability to recover the files into any subdirectory we want, without overwriting the original files.
Immediately after the ‘cd /’ command is where you would put any commands to shut down all services that must be quieted prior to a backup. The example script has a (commented out) command to initiate an Oracle database shutdown followed by a ‘sleep’ command to allow time for the shutdown to complete. The example database shutdown and the following delay probably don’t apply to your system. Obviously, you’ll have to add commands yourself to stop any applications that might interfere with the backup.
Next, we use the ‘date’ command to create two sets of four tiny files to stick at the start and end of each tape. Note that the presence of a ‘date.#’ file at the beginning of each tape lets you quickly find out when a tape was created and on which drive. The ‘zzzz.#’ files, appended to the end of each tape, only serve to let you easily verify that a backup completed without overrunning the end of the tape.
Next, we start the four actual ‘tar’ backup commands, each with sample directories named ‘./dir1’, ‘./dir2’, etc. Of course, you’ll need to modify the list of directories to match the actual directories you wish to back up. Note that you’ll probably want to balance the directory sizes so that all of the largest directores aren’t on the same tape. Also, note that each ‘tar’ command is run in the background and logs to a tar.#.log file in the /tmp directory. Obviously, you might want to put the logfiles somewhere else.
After each ‘tar’ command there is an entry like this: ‘TASK=$0’, or ‘TASK=$1’. These arbitrarily-named ‘TASK’ variables are used to store the process ID of each ‘tar’ command so that the script can wait for them with the four ‘wait’ commands that follow in the next block of code. There, we have the four ‘wait’ commands waiting on the $TASK0, etc, variables. (The addition of the ‘$’ to each TASK# shell variable is not a typo -- it’s necessary to read back the contents of the variable.)
Next, after the script has waited for the completion of each of the four ‘tar’ commands, it appends some information to a history file for later reference. It stores the date of the backup, the filesize of the logfile, and the number of files backed up on each tape to each of four history files. While the script will overwrite the logfiles (tar.#.log) each time it is run, it will append these three lines to each of the four history files (tar.#.history).
The final steps in the script are commented out. Those are the commands necessary to restart any applications that were brought down for the backup. Again, in the example we assume an Oracle database needs to be restarted. You’ll need to add the commands necessary to start any applications that were stopped at the beginning of the script. |

Create Ubuntu snapshot backups with FlyBack |
vote
|
|
| FlyBack is a tool similar to Apple's TimeMachine. It is intended to create snapshot-backups of selected directories or even your full hard drive. From the FlyBack project page: "FlyBack is a snapshot-based backup tool based on rsync. It creates successive backup directories mirroring the files you wish to backup, but hard-links unchanged files to the previous backup. This prevents wasting disk space while providing you with full access to all your files without any sort of recovery program. If your machine crashes, just move your external drive to your new machine and copy the latest backup using whatever file browser you normally use." This article shows how to install and use FlyBack on Ubuntu 7.10 (Gutsy Gibbon). read more... |

Tutorial: Making Linux / UNIX snapshot backups |
vote

|
I’d like to configure my Debian box to backup two remote servers using rsnapshot software. It should make incremental snapshots of local and remote filesystems for any number of machines on 2nd hard disk located at /disk1 ( /dev/sdb2). How do I make backups?
rsnapshot saves much more disk space than you might imagine. The amount of space required is roughly the size of one full backup, plus a copy of each additional file that is changed. rsnapshot makes extensive use of hard links, so if the file doesn’t change, the next snapshot is simply a hard link to the exact same file. read more... |

Tutorial: Automate remote system backup with rsync |

This article comes complete with example shell scripts and crontab entries.
In this article we explain how to automate the backup of files on remote machines to a centralized server using rsync.
rsync is a command line utility that is used to synchronize files between two computers over a network to synchronize files between two filesystems. It was written as a replacement for rcp but with many new features. For example it uses an algorithm that will only transfer files that have been modified. SSH will be used to authenticate between the machines and to encrypt the network traffic. read more... |

TimeVault: Ubuntu backup made simple |
vote

An in-depth review with plenty of screenshots...
While it's always been possible to use tools such as cron and rsync to backup files in Linux, there has never previously been an easy-to-use program that end-users and beginners could feel comfortable configuring, until now. TimeVault allows you to backup your system with snapshots; this means that if you loose a file (or an entire file system), or want to return a document to a previous state, it is as simple as selecting the file through TimeVault's Snapshot Browser and clicking "Revert." Though it is currently in Beta, I have found TimeVault to be a complete solution for backups, and as of yet haven't discovered any single major problem. read more... |
