Hi, Does anybody know of a good hard drive morroring tool? I'm not even sure that's the right name, but I just ordered two 200gb drives thinking I would set up a raid on my mame machine to backup my music, roms, artwork, etc. but now I'm thinking I really dont need a raid since I don't care about backing up programs and I'd rather not deal with the setup if I don't have to. I'd just like a tool that could check the files in a given directory every day or two and copy any recently updated files to another drive. A restore feature would also be nice. Thanks! -TJ |

After a few years of sporadic data loss, I got smart and started using No Hands Backup. Here's the installer for the version I use (this version is from when NHB was free software). It's old, but still quite adequate. I use it on W2K, and I know of several people that use it on WXP. www.crazybaldman.com/stuff/no_hands_backup_2.5b5.exe There are newer versions, but his software is no longer free, so if you want a newer version, try out his 30 day demo, and you may be thrilled to register it for only $16. http://www.nhbackup.com/ (Note: I am not connected with the author of this software in any way other than that I use his software. Also, I do not believe I am violating any copyrights by posting this free software for download. If you are the lawful owner of this software copyright, and wish me to remove this download, please advise me via email, you can email "art" at the above domain. Thanks!) Chemame |

Another option, albeit verrrry unglamorous. My Windows drive gets Ghosted but I also have a few key directories that I back up nightly, using just a scheduled DOS batch program. Plain old XCOPY works great. With the proper switches it will do exactly what you are asking. An example of the Xcopy command, with the switches you'd need: xcopy <from dir> <backup_dir> /s /k /d /y For me, it works great and runs in the middle of the night. The amount of data that changes daily is relatively small so the jobs run quite fast. |

My backup copies to a 2nd hard drive and to another PC over my wireless network. Brad |

RAID1 or RAID0+1 you would need a raid controller. Using a software raid system requires your CPU to run the disk access slowing your system down. Taking your setup (2) 200gb drives you would set them up as a raid1 mirrored set and an OS; windows probably, would simply see this as a single 200gb drive. each write gets sent to each drive so both drives are duplicates/mirrors of each other. If one drive fails the raid controller simply points itself to the second drive. If you don't have alerts or drive lights you might not even realize that you have a drive failure. That is what mirroring is for complete hard drive redudancy. Nice option as you don;t need to check backups have completed or did I back that up, you get the picture... |
