Approximate ratio of backup time to validation time
Can anyone authoritatively state whether there is a typical rough ratio between the amount of time required for a specific backup and the amount of time required for its corresponding validation? My Disc/partition validations (one Vista computer and one Win 7) take almost as long as the original backups. I am trying to figure out if the valididation is really finished much earlier but the validation measurement feature is faulty (110 days to go, etc.) and keeps it running. Or, maybe the validations actually do take about as long as the corresponding backup. Even if others have had my experience, that would not tell me what I need to know--Are these validations finishing at 100% and going to 1000% and wasting much time, or do they really always have to take about as long as the backup? I hope an Acronis rep speaks up.
@ seekforever, it still seems to be the case. My latest differential was being validated for about two hours despite its relatively small size (2-3 gigs, don't remember exactly).
This would be more in-line with the full+incremental (about 70 gigs).
The time calculating checksums is probably extremely minimal compared to disk read/write times. A backup, unlike validation has to do writes as well as reads, however, most backups are done using two diff disks so the PC can be writing while it's reading. Of course, this is more effective if the two disk are not on the same channel. so I'd expect the times to be very close.
My system disk makes a 17Gb backup and it takes approx 9 minutes to create a full backup and approx 6 minutes to validate that backup.
Hello all,
Thank you very much for your comments.
We just released a new build and the validation issue has been successfully resolved.
I would like to lock this topic so that any issues can be discussed in the main topic. This will really help us if we keep discussing this problem in one place.
Please check this link for the main topic and my announcement in it.
Thank you.
