Back-up Software (Mirroring)

nasu

Hi everyone,
I have a file server with about 500GB + of important software that I would like to back it up to an external e-sata hdd (1TB) automatically everyday. I need a good software open source or even commercial that moves the files from one location to the external HDD without making any special sort of a file format like windows tool does .bak or something just purely moving it like RAID 1 does AND also u can specify features as only make sure copy everything that A drive has to B drive has and if you find a deleted file from drive A don't remove it from hard drive B.


Many thanks,
George

I need to mirror a file server on the weekend. This should the trick nicely.

Be sure to set the wait and retry values:

/r:<N>

Specifies the number of retries on failed copies. The default value of N is 1,000,000 (one million retries).

/w:<N>

Specifies the wait time between retries, in seconds. The default value of N is 30 (wait time 30 seconds).

That's a long time to wait if it gets stuck on something

any other tools ?

Because I love robocopy so much, I'll expand on what dynamic said in case anyone is confused.

In case no one knows, Robocopy is standard in Vista....but if you have XP or earlier you will have to download the Windows Server 2003 Resource Kit Tools and install that.

Create a batch file and use the code below, changing source and dest to match your needs. Then use Scheduled Tasks to run the script daily. This will do exactly what Nasu is asking for. It will look for any changes from \ and 'replicate' them to K:\ daily.

@ECHO OFF
SETLOCAL

SET _source=D:\Music\

SET _dest=K:\Music\

SET _what=/COPYALL /B /SEC /MIR
:: /COPYALL :: COPY ALL file info
:: /B :: copy files in Backup mode.
:: /SEC :: copy files with SECurity
:: /MIR :: MIRror a directory tree

SET _options=/R:0 /W:0 /LOG:MyLogfile.txt /NFL /NDL
:: /R:n :: number of Retries
:: /W:n :: Wait time between retries
:: /LOG :: Output log file
:: /NFL :: No file logging
:: /NDL :: No dir logging

ROBOCOPY %_source% %_dest% %_what% %_options%

We use a program called MirrorFolder in our shop on a couple of servers, works well. It is also used to mirror our users mailboxes in real-time since our mailserver software doesn't have such a feature for redundancy and it holds up to 1500 accounts without incident or any slowdowns.

MirrorFolder: A real-time backup software

For those using Robocopy, check out Robocopy + PowerShell:

We run Acronis on about 500 server .. Linux (IF ext3 is used) and Windows (2008 compatible) and for our lab we run Acronis on a server and grabbing them via PXE - brilliant ..

Edit: oh, you don't want any other extension just normaly A <> B .. never mind then ...
