Multibit security with regards to “backup” folders

1

I'm using the MultiBit client to manage my wallet (right here on my computer), but I am concerned about the security with regards to the *-backup folders that it creates automatically.

When I inspect the wallet-unenc-backup directory, I find 2 pairs of .info and .wallet.cipher files. Using a text editor, I can see that the .info file only contains my public bitcoin address and a line referring to the rolling-backup directory and some other numbers. The .wallet.cipher file shows weird characters.

Does the .wallet.cipher file contain a private key unencrypted? If so, why does the client not warn me about this? Is it because its users are expected to know this, or am I wrong about this?

The other folders contain .info files as well, and .wallet files (probably and encrypted wallet).

Any clarification on the actual information stored in these files and whether that information is encrypted would be helpful.

I did read the documentation of MultiBit,...

Wallet backups

You can always recover your bitcoin through your wallet words (seed phrase).

So long as you know your wallet words (or your KeepKey and PIN if you are using one) you can use a wallet backup to recover:

your bitcoinyour contacts and notesyour payment history and notes.

Hardware and software can fail, be lost or stolen. MultiBit HD ensures that an automatic encrypted backup is made of your wallet to a location that you specify.

Use a cloud backup service

Setting up a cloud backup service is straightforward and for small amounts of data (under 2GB) it is often free. We would strongly urge you to consider SpiderOak for its end to end encryption. An alternative is Dropbox which is extremely common and provides an excellent user experience.

MultiBit HD encrypts all your cloud backup information using a strong AES key derived from either your wallet words or from a password provided by your KeepKey. It is...

MultiBit is a popular Bitcoin wallet program that aims to combine fast startup times, a simplified feature set, and support for multiple languages.

This guide documents MultiBit through step-by-step examples written from the perspective of a reader new to both MultiBit and Bitcoin. Having access to a small amount of bitcoin will make the examples presented here easier to understand. Many purchase options are available; U.S. residents can even pay for bitcoin with cash at a bank teller.

MultiBit Classic and MultiBit HD

Work toward a new variant of MultiBit wallet, “MultiBit HD”, was recently announced. MultiBit HD implements the HD Wallet proposal found in wallets such as Electrum.

The MultiBit team has proposed that updates to the currently-available version of the software would continue to be released under the name “MultiBit Classic”. The information presented here applies to this version of MultiBit (0.5.17).

I'm having a bit of an issue with my backup script. It uses a for loop to archive anything within a given directory using tar. It lists the directories perfectly and creates separate archives for each directory how I'd like them to be, but the variable isn't listing the path to the directory to backup. Can anyone give me an idea of how to make sure the variable is populated with the correct information?

Here's the script:

#!/bin/bash set -xv dirs=$(ls /home/phoenix/testarchive) dest="/home/phoenix/backup/" archive=".tar.bz2" clear echo "Archiving data..." for dirs in $dirs do echo "Archiving $dirs..." tar cjf "${dest}${dirs}_$(date +%F)${archive}" $dirs echo "Archive complete!!" done echo "All archives created!!" echo "Test created archive to ensure validity." ls -lh $dest

And here is my error output:

echo "Archiving data..." + echo 'Archiving data...' Archiving data... for dirs in $dirs do echo "Archiving $dirs..." tar cjf "${dest}${dirs}_$(date...

Backup lets you back up data to a file or to a tape. When you back up data to a file, you have to designate a file name and a location for the file to be saved. Backup files usually have the extension .bkf, but you can change it to any extension. A backup file can be saved to a hard disk, a floppy disk, or to any other removable or nonremovable media on which you can save a file.

When you back up data to a tape, you must have a tape device connected to your computer. Tapes are managed by Removable Storage Although Backup works together with Removable Storage, you might have to use Removable Storage to perform certain maintenance tasks, such as preparing and ejecting tapes.

The following four steps describe a simple backup operation:

Select files, folders, and drives for backup

Backup provides you with a tree view of the drives, files, and folders that are on your computer, which you can use to select the files and folders that you want to back up. You...

You are not limited to backing up the files that Norton automatically detects and places into its file categories. You can add files to the set of files to be backed up, and you can exclude files from being backed up as well.

Norton lets you select a file or folder from your computer that you want to include in your backup. The option on the What tab in the Manage Backup Sets window provides you the options to add files and folders to a backup set.

You can also right-click a file or a folder and add it to a backup set using the Norton Security option on the shortcut menu. The shortcut menu is available after you configure your backup and when the Manage Backup Sets window and the Restore Files window are closed. When you add a file to the backup set, Norton lists the information in the window that appears when you click option. You can view all the files and folders that you added to the backup.

You can also remove an addition from the list of items that is...

How to secure backup?

Folder Lock offers secure backup of your encrypted data to an online storage. Unlike other backup and encryption programs, Folder Lock has come about a full circle towards integrating its security in the cloud, by keeping your data encrypted for backup, even while you are working on your files or modifying them on your PC. No need to decrypt or manually backup your files.

Furthermore, the backup and restore transmissions of these files take place using 128-bit SSL connection, proven to keep the bad guys from intercepting encrypted data. Since data is encrypted at both ends, there is never a risk of data availability without a correct password; securing your confidentiality by protecting you from data-loss. You can later restore files at any time, on any computer, and in any device by providing a correct password.

Step 1

To start backing up your encrypted files, you must sign up for a Secure Backup account. If you have already...

Hello

flyfoam

,

Which filesystem did you format your NAS? Is it possible for you to attach it to local PC and backup directly (it will help us to exclude network connection as the cause)?

Please also follow to Tools -> Options -> Default Backup Options, then reduce Network Speed setting by half.

Acronis True Image needs at least 2 simultaneous inbound connections to a Windows network share: Data connection and Control connection.

Windows XP Home Basic and Windows Vista Home Basic limit the number of simultaneous inbound connections to 5.

Windows 2000, Windows XP Professional, Windows Vista Home Premium and Windows Vista Ultimate limit the number of simultaneous inbound connections to 10.

Windows Server operating systems do not have a limitation on the inbound connections.

To see how many inbound connections are attempting to access the shared folder, do the following:

Hello

I want to backup a database to a network share.
I cannot do that because sql agent service is running as "Local System" and the job is not allowed to write on the network share.
I wonder if it's possible to find a workaround to this, without changing the sql agent "Local System" logon user.
Thanks

In the first five of articles of the "Backup How-To's" series we have discussed the main principles of data backup and benefits that backup software brings. Now it’s time to look more closely at particular methods of organizing data protection. In this article we will review different aspects of files-based backup in home environment.


Backup at Home

To start with, let’s recall what kind of data is considered important by home users and demands backups. The most frequently modified files include e-mail messages, notes and calendars, contacts and Internet Favorites. Less regular but probably more valuable data include digital photo and video archives, music libraries, data of different applications and Windows settings (registry). Then it is the turn for “common” files and folders including the My Documents folder, Desktop, etc.


Tasks and Presets

The practice shows that backup software with task-based architecture provides the most convenient...

So you have deployed Microsoft Exchange 2010 in your enterprise, and you are now sitting back and enjoying this state-of-the-art enterprise mailing solution when, suddenly, you realize that you seriously need to backup this business-critical data (which emails have become, for any business today).

Before rushing out and investing in 3rd party solutions to protect your data, why not first inspect free and built-in alternatives to see if they can fit your business needs?

In this article I will cover the essentials of how to backup your Microsoft Exchange 2010 databases using Windows Server Backup, which ships with your Windows Operating System (and thus is essentially free of charge). While this is a quick and effective basic solution, I will also go on to highlight the shortcomings of this solution compared to other, more expensive solutions. If you follow each of the steps I describe, you should find your experience to be similar to the screenshots I’ve provided as...

What Is File Backup?

The most used and most popular backup methods are System Backup, Partition Backup and Disk Backup. These three backup modes can provide user useful and effective ways to create full backup for their partition, system or even the entire disk. There is no doubt that full backup is the powerful and efficient way to enhance data security, however, it still has its deficiency in storage space and processing time consuming. What should you do if you just need to backup a specific file or folder? Partition Backup and Disk Backup will absolutely backup the files or folder you want, but it will also backup those files and folders you don’t need. In order to solve this problem, AOMEI Backupper provides a new feature to deal with those kinds of tasks -- that is File Backup.

File Backup refers to backup a specified file or folder to prevent data loss. For instance, you can create backups for your family pictures, favorite music or other user files. File...

Three Methods:How to Backup Exchange Server 2003 With NTBACKUPHow to Backup Exchange Server 2010 With Windows Server BackupCommunity Q&A

Exchange servers must be backed up regularly to ensure that all mailboxes and system data can be recovered in the event of an Exchange server crash. Because Exchange uses open files and running processes, backing it up is a more complex task than backing up flat files. Microsoft backup applications and third party backup software can be used to handle Exchange backups. Microsoft Exchange Server 2010 offers a plug-in for Windows Server Backup that provides easy, successful Exchange-aware backups. Older versions of Microsoft Exchange can be backed up using NTBACKUP, a built-in backup...

It is likely that the bulk of Windows users make use of the user folder and its directory structure to save files and documents important to them. The My Document, Music and Picture folder are often used to save files of the type, and it is only natural to take those files with you when you move to another system or install Windows anew.

While you could go ahead and backup those files manually, for instance by burning them to DVD or moving them all into a folder that is synchronized with the cloud, you could also try Gotcha Backup Utility for that task. The program serves only the purpose of backing up user data folders so that you can restore them to the same or another computer system at a later point in time.

Unlike other programs of its kind it not only detects the user folders of the system you are currently logged in, but also those of other Windows installations that may reside on the computer. That's helpful if you have installed Windows on a new hard drive...

Wow, you're totally right -- I didn't read that error message closely enough.

I looked at this more closely using the REALLY helpful echoargs.exe utility included in the PowerShell Community Extensions (http://pscx.codeplex.com/):

PS C:\Windows\system32> c:\temp\echoargs.exe start backup -backupTarget:\\fso\core\backup\ "-include:C:\Users,C:\Program Files" -vsscopy -quiet
Arg 0 is
Arg 1 is
Arg 2 is
Arg 3 is
Arg 4 is
Arg 5 is

So it looks like if you put double quotes around the entire -includes parameter, you get what you want. Surprisingly, it seems like you don't need to mess with more nested quotes to get the directory with a space in the name to work. Here's me running the command on my Windows 7 machine:

PS C:\Windows\system32> wbadmin start backup -backupTarget:\\fso\core\backup\ "-include:C:\Users,C:\Program Files" -vsscopy -quiet

Today I will show you how to optimally backup all your personal files, folders and data in a way that can be easily read and used in any operating system, not just Windows.

As I have mentioned in previous guides, Windows Backup & Restore is great if you are sticking with a Windows operating system, but messy and complicated if you want to use that backup in MAC or Linux (it’s inside a container file) and System Repair Discs are only good for your Windows system, not your personal data. It is far better to manually backup your personal data, preferably in addition to Windows built-in backup, rather than relying soley on the Windows backup format.

Before we begin, you will need either a USB flash drive or external USB hard drive (see example images below) with the capacity to hold all your personal data, which I will go through with you first, before commencing the actual backup process.

Backing up your files is an effective way of protecting your data against data theft, hard disk failure, malware infection and many other unpredictable events. Experts agree that backups should be saved away from the source, so in case of physical damage like fire, the backups stay safe and secure. Cloud storage services provide an excellent way of backing up files. The free Duplicati program allows you to backup your files across a number of well known cloud storage services like Amazon S3, Microsoft Skydrive, Google Drive and more.

Here are some of the features of Duplicati :

It uses AES-256 encryption to encrypt all your data before upload. It supports incremental backups to save bandwidth It supports backup scheduling to automatically backup your data. it supports many targets like FTP, Cloudfiles, WebDAV, SSH (SFTP), Amazon S3 etc. It allows you to selectively filter which type of files or folders you want to upload. it can backup even in-use or locked files both in...

Why Backup Your NAS Drive to The Cloud?

Your data is precious and often valuable, so we should not need to impress on you the necessity of reliably backing it up, and this is as true with data stored on your NAS drives as it is of any other data. The obvious solution is of course to backup to a (or more than one) local drive, either through routinely connecting it to a computer via USB, or using a file syncing program such as GoodSync or Allway Sync.

This is all well and good, but following a principle that we have talked about before, the famous 3-2-1 principle which holds that data should be backed up in three different places – two different media for local storage (for example the NAS drive and a local PC’s hard drive, preferably configured for RAID backup for additional redundancy), plus one offsite location, it is prudent to also backup to the cloud. After all, a burglar could make off with all your hardware in a single location, fires are always a danger, or...
