Just to add four hours of pointless wasted time on to what should have been a five minute backup of my C partition on my HP m7170n before a reload, I downloaded and installed update #3677. Because - you know - it now works with DVD discs, hooray. Removed the previous version - 2337 and installed 3677, tried to back up the small C partition on my XP Pro machine using Backup - entire disc etc, usual steps. Backing up to the same USB Maxtor external drive I have been using in v 2337. TI starts the backup and then - nothing. Just sits at zero percent complete. Log shows last entry of is locking the C partition but then stuck and nothing actually runs. Tried D partition and even individual files - nothing. Tried the forum tech support patent answers of ACPI, logging off, etc - nothing. Set options to not backup system, temp, hidden files - nothing. Moved the paging file to D partiton, ensured no other non-XP services\apps running, no anti-virus or firewall (no threads for either) - nothing. Well at least I can use DVD's now - Tried to use various DVD's after another hour reading through forums to find out what actually does and does not work - most does not obviously - used the same DVD's some got to work - mine failed. Hopefully some day, some release future etc advises Acronis - after sending me email announcing the exciting new DVD feature! Uninstalled after hours of wasted time and put 2337 back on - ran the backup to my USB Maxtor drive with no problem. Nothing changed, did numerous clean installs of both other versions, checked and removed all prior Acronis entries\files before giving up on both and going back to 2337. No problem on the Maxtor and no change to it between versions other than it growing bored and older. 2337 is the ONLY version that has ever worked on my PC's and it is not consistent or reliable. I have never, in forty years of buying and using software - felt more ripped off than I have by Acronis. Every single release has been a time-consuming, frustrating battle with bugs and failures and requires more time spent looking for solutions to even basic operation on the forums than the entire reformat and reload of the OS takes. Acronis clearly feels it is perfectly reasonable to expect customers to spend HOURS dissecting bugs and problems for what should be a ten-minute backup. Tech support offers the same impotent mantra of ACPI, logging and send us your sysinfo but fails to provide the features claimed (DVD) or even stable, reliable software. You'll delete this of course but if I had the time and resources, I would sue you for failing to provide anything close to the advertised product. As it is I'll settle for letting everyone I can know how awful your software is. Good riddance.
