Two Apps That Make Backup Less Chore, More Lifesaver
Jul 14, 2010 5:00 AM PT
Backing up data on my multiple Linux computers has always been a gray area for me. The process of backing up data for me boiled down to convenience and cockiness. I thought my no-app backup procedure was a better option. That twisted view nearly resulted in a data disaster for me recently.
Having multiple computers all storing the same data tends to make reliance on an actual backup application seem to be a needless redundancy. But a round of system failures put my access to backup data at risk. This led me to search for open source software to ensure that my data was there when I need it.
My search yielded two pleasant results. I found an impressive lineup of open source backup apps. After trying out a bunch, I've placed two key backup tools at the top of my list. Deja Dup Backup Utility and LuckyBackup both are easy to use offer more than the bare-bones features typical of this software category. Both are ideal choices for personal use as well as small-business data archiving.
Why the Need?
Dealing with data backup is really an exercise in being prepared. In my case, I store my primary data on a large capacity thumb drive. I use this USB device to access and save all my working files as well as my data archives. On my two desktop computers, two laptops and one netbook, I routinely copy the open files to the hard drives as I move from computer to computer using the syncing feature of a file management program.
In theory that gives me two copies of all my stuff at all times. Plus I have two external hard drives onto which I periodically perform similar directory-syncing operations. So trusting in the false assumption that my data backups were under control, I did not use a bona-fide backup app regularly.
So much for false assumptions. On a recent trip I lost the file-encrypted master USB storage device. That left me with just the hard drive's content on the laptop with me. A quick fix involved buying a new USB drive and dragging all the data to it from the hard drive.
Backup Apps Still Needed
Soon after, however, a series of hardware failures struck that put what I thought to be a foolproof system in question. A relatively new desktop crashed and burned. That necessitated a full data retrieval for its replacement from one of the external hard drives.
Soon after that, not one but both laptops had their power cords short out. That obviously caused limited or no access to the data kept as backup on the hard drive. In both cases the batteries hadn't charged as part of the cords' malfunction. I just didn't notice the notification icons telling me that the batteries were discharging.
As unlikely as this equipment failure scenario may seem, it happened. My carelessness and the distractions of working while traveling caught me off-guard. I learned that even fail-safe data plans need a backup. I did not suffer any permanent critical data loss. But if I did not have data stored on multiple locations, that outcome would have been much more likely.
I almost learned my lesson the hard way. In case lightning strikes with more force, now I am better prepared to ward off data loss woes.
Deja Dup is a simple backup tool. It reinforces the right way way of doing backups without being complicated to use. It builds in file encryption, regular off-site storage and includes duplicity as the back end.
Using LuckyBackup is a lot like using a CD/DVD burning application. The menu makes it that simple to identify the source directories or files and the target backup location. It is a powerful, fast and reliable backup and sync tool.
I always prefer software that comes with choices. I'd rather work my way than the way a program writer thinks I might work. Both Deja Dup and LuckyBackup meet that test of acceptability.
In Deja Dup program options are set in Edit/Preferences and in the backup panel. The options include location of directories and files, whether or not to encrypt the backed up copies, what (if any) files in a directory to exempt and whether or not to automatically back up files on a schedule.
LuckyBackup's choices are a bit more extensive. A profile option lets you create and maintain numerous backup scenarios. You also create a list of tasks for backing up in each profile and can select which ones to run from a task list window. Clicking the Advanced button in the task properties panel exposes numerous other include/exclude options.
There is no file encryption, however. LuckyBackup is an application for data back-up and synchronization powered by the rsync tool. Rsync is an open source utility that provides fast incremental file transfer. Automatic scheduling is also an option. Even better, a Cron It feature lets you run the backup routine as a pre-selected time interval without having to load the program's GUI. Pretty nifty!
A major difference separates these two backup apps. In fact, the difference is so critical that this area no doubt will help you decide which one to use.
Deja Dup is driven by the concept that off-site file storage is an absolute necessity. If you use this app, then you cannot save your backup file library locally. You must select a server service.
The set up is easy. Just click the Server button to reveal the choices and the configuration panel. The choices are Public FTP, FTP (with logon), SSH, Windows share, WebDAV, Secure WebDAV and custom location. For this last choice you must specify a valid URL. You cannot divert the backup storage to a local external drive.
With LuckyBackup, you specify the type of backup (entire directories or selected files, for example) when you add tasks to the task list. It is here as a task property that you specify the destination of the targeted backup files by scrolling through a directory tree.
One failing of many backup apps is their reliability. By this I mean you don't know if your selected options and directions to the program result in a successful backup operation. Often, you learn when you install a backup that you forgot an essential directory or some location was not properly entered.
By then it is too late. Not so with LuckyBackup. The program has two levels of testing to ensure you get exactly what you intended in the backup routine.
The task properties panel has a button labeled "Validate." If you have unworkable directions, the app will alert you. This feature is somewhat like the proof function before you complete your report in tax preparation software.
A second failsafe feature in LuckyBackup is the simulation function. If you are not sure of your backup settings, just click on the Simulation button. LuckyBackup will perform a trial run that does not make any changes.
A feature that I love and wish all backup apps included is the ability to synchronize files and directories rather than do a complete or incremental backup operation. The Sync feature duplicates the contents of directories with files that were most recently modified.
As a user with multiple computers and a flash drive intermediary, this is extremely useful to me. I use the Krusader file manager's directory sync feature for this same purpose. But being able to have this capability within a dedicated backup app will ensure that I actually back up files regularly on all of my computers.
