Due to the imminent demise of my old tape drive I have been searching many weeks for a viable replacement backup routine. I have a 2 PC configuration both on XPsp2, connected through a router. I have tried many backup programs (NovaBackup, BackupAssist, YTBackup, etc, etc) but none seemed to quite fit the requirements. By accident I stumbled upon Acronis TI v.10. I converted an old HD to USB, atached it to the pc host and installed v.10 on both machines. Wow! is all I can say. This program is very fast and appears to be accurate. During the past week I have wiped the system drives several times on each machine and recovered both faultlessly, in minutes each time. There were a couple of wrinkles in all this. In creating the bootable recovery DVD, the default option is to include both "Safe" and "Full" versions of TI. This done, when the machines were rebooted in recovery mode, TI would not see the USB drive across the network. Tweaking the network settings did not help. Created a new bootable disc but this time deselected "Safe" version. It worked like a charm. I have never been a fan of incremental or differential backups - too confusing. Yet I could not clearly see from the User Manual how to append full backups to the USB drive. A recent post by "Catfan432" explained the solution nicely so thanks to he/she for this insight. In summary, TI is an elegant solution with a short learning curve compared to other backup programs I have tried. Well done Acronis.
