This is a simple command line utility for backing up files to Azure Blob Storage. It's main intended use is for scheduling backups using the task scheduler in windows.

This is only a file backup to and from the blob storage service, there is no support for backing up other services on Azure.

Install and configure:

There is no installer, download the package and unzip it into a folder (for example into C:\Program Files\AzureBlobBackup\).

You can specify your azure account connection string either in the AzureBlobBackup.exe.config or as a command line argument
using the --account switch.

An account connection string consists of your storage account name and the shared key, for example (all on a single line):

"DefaultEndpointsProtocol=http; AccountName=storageaccount; AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw=="

Sample use:

This is a command line utility, either schedule it using task scheduler or run it manually by opening a command prompt (cmd.exe)

Backup folder "C:\files" to azure container "backup" (account in config file):

AzureBlobBackup.exe --backup --source=C:\files --destination=backup

Backup folder "C:\files" to azure container "backup" (account specified on commandline):

AzureBlobBackup.exe --backup --source=C:\files --destination=backup --account="youraccountconnectionstring"

Restore files from azure container "backup" to "C:\files" (account in config file):

AzureBlobBackup.exe --restore --source=C:\files --destination=backup

Clean files in azure container "backup" that is not in the local folder "C:\files" (account in config file):

AzureBlobBackup.exe --clean --source=C:\files --destination=backup

If you want the utility to write detailed output for each file use the --verbose option. To see all options use the --help option.
