Any software to do minute by minute backup?

Question

Of all the freeware backup programs i've checked out, the most frequent backup i could do automatically was every hour :( Is there any freeware out there that can backup my data every minute or so? :) I'm talking about a few mega bytes of VERY important data... Preferably over the LAN backup too :)

Answer 1

Another couple of options you could take a look at:

File Hamster DocShield

There are free versions of both.

One other option for continuous backup would be Comodo Time Machine

However, some users have had problems with the software, so I'd suggest taking a look at the forums before you install this:

Comodo Time Machine - CTM

Answer 2

I'm not aware of any freeware to do real-time or CDP. If the data is that important, you might have to pony up for some software.

You could try scheduling software like robocopy, rdiff-backup, or something else to run every minute or so. If the files you want to back up are going to be held open, you'll need to handle that somehow. For Windows, you'll need to use VSS, a.k.a Shadow Copies. Adi Oltean's Blog has several posts on mounting VSS snapshots to make them easy to copy from, if you're using software that's not VSS-aware. HoboCopy may also be useful.

Answer 3

What about Dropbox? Set your editor to save it every minute and Dropbox will save it every minute. Also you can revert to previous versions on the Dropbox website. (There is a policy about overuse but I guess you won't edit it 0-24.)

Answer 4

On a Unix system, you could roll your own bash script for doing this. You could use 'rsync' to backup any and all changes in one or more directories to an external drive, or to an external machine (if you have ssh connectivity). You could do this in windows also, by installing cygwin and making sure you include rsync (it may be part of the default cygwin, but I'm not sure). Your script could do a loop, sleeping for 1 minute between backups. You could also have the script just do a single backup and schedule it via cron (in Unix systems at least) once per minute. To backup up directory /foo/bar from your localhost to /backups/mymachine/foo/bar in a remote host, you could do:

$ rsync -zave ssh /foo/bar/ remotehost:/backups/mymachine/foo/bar

Answer 5

I always use cron and rsync for backups. Make a script like:

#!/bin/sh
#/home/ranhiru/bin/backup.sh
# KEEP SLASHES!
src=/home/ranhiru/Movies/
dst=/home/ranhiru/backups/Movies/
host=remote.server

rsync -a -q --partial --size-only $src/ $host:$dst/

and make a file:

#/home/ranhiru/.crontab
# cron needs PATH variable set
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin
# run this script EVERY 2 MIN
*/2    *    *    *    *    /home/ranhiru/bin/backup.sh

run

chmod u+x /home/ranhiru/bin/backup.sh

and finally,

crontab /home/ranhiru/.crontab

Have you taken a look at SyncToy and scheduled tasks in Windows?

Answer 7

If you store your files on ZFS, either locally with [Open]Solaris or FreeBSD, or remotely if you run any other OS, you might do a snapshot every interval you like and then do a differential incremental send to your backup platform.

Answer 8

I have been pleased with a program call SyncBack available at http://www.2brightsparks.com. A free version is availabe (truely free, not just free to try) that utilizes the Windows Task Scheduler to schedule the backup jobs.

Answer 9

sorry, but why don't you just get another harddrive to mirror your primary drive? That way everything written to one is written to the other... live. Raid 0 compliant.

This really sounds like you probably could use a raid solution. Is this data already hardware level protected? If it's just on a PC, you can probably add a raid controller card to it for the extra drives to be setup. If it's on a server, it probably has a raid capability on it. You don't mention what the PC it is, other than windows. what version of windows? What sort of hardware (PC? Server class?)

Shamless promotion: I suggest www.FolderTrack.com. It does a backup up of every save, delete,rename,or file change. It does not have an online backup component but it does have the fine detailed backup that you want. The software is free using discount code: bos
