Differential backup, initial full backup in multiple parts - ?
I created a differential file backup with the initial full backup occuring on 3/9/2014. I'm used to seeing the initial full backup being a single file (in my case, around 100GB). However, in this set, it's broken into the following files:
MyBackup_full_b1_s1_v1.tib 3/9/2014 7GB
MyBackup_full_b1_s1_v2.tib 3/9/2014 43GB
MyBackup_full_b1_s1_v2.tib 3/9/2014 47GB
The backup seems to be working, i.e., I can use Recover and see/work with files, but I want to avoid having some issue down the road. So far, my experience with Acronis has been a bit rocky...
Sorry, I did have a typo. The exact wording of the files are:
MyBackup_full_b1_s1_v1.tib 3/9/2014 7GB
MyBackup_full_b1_s1_v2.tib 3/9/2014 43GB
MyBackup_full_b1_s1_v3.tib 3/9/2014 47GB
I haven't done a restore or updated anything, nor made changes to the backup task. This is in a folder on a Western Digital NAS drive with almost a terabyte free space. It's accessed via wifi.
The file naming-numbering isow correct and no problems apparent.
The numbering says this is the first backup on this task. Was the single file not Wifi? or how did the two tasks differ that might cause the split/nosplit comparison?
This was definitely the first backup (the initial full backup), and it was on wifi. There's no difference in how this one was done vs. the other tasks I've tried (and had issues with).
So, having them split like this is normal/fine? Just seems odd to me... My wife's machine is setup with an identical backup task, and her initial full backup was one file.
This may have occurred due to a temporary loss of WiFi signal, degradation of signal, or low bandwidth. What distance and how many and type of obstacles are between your machine and your WiFi router?
I have a pretty good connection typically, 802.11ac at 390Mb/s. However, it's entirely possible that I have intermittent connectivity issues.
So, if that's the case, does it mean that I have a good backup, it's just that Acronis needed to restart the backup after a disconnect and that's why the files are broken up?
The only way I know to verify if the backups are good is to test them and see. You can run validation of course but that doesn't in all cases guarantee the backups are good. I am only making an educated guess here as to the breakup of the backup file. It would stand to reason that this might have caused your backup being split as it were. I would suggest running some network logs on your LAN and see if you can tell if there are times when the bandwidth drops off significantly or connection drops out or something else along those lines. If you find this to be the case correcting that issue may solve the other. If such a condition cannot be found then there is something else going on here all together.
Okay, I'll check all that out. Thanks for your help.
I'm wondering if maybe retiring that backup task and creating a new one is a good idea. If it does the same thing again, that would indicate some issue with my machine that needs rectifying.

Good thought it seems to me like, could be something specific with the task itself although task creation is pretty straightforward. You just never know though. If you have a number of backups already made that you would like to save you can do that but at this point I do not think that is the case. If so however that is doable.
I just created a new, identical task, and ran the initial full backup. This time, it created a single file of about 100GB. So, it looks like it might have been transient network issues or something when the initial backup ran on that other task.
Hopefully this one will be a keeper.
Curious: check your log files on the split files backup and see if there is an info message.
Yes, it does show errors writing to the file. So, I'll assume there were either problems with the network or with the NAS during the backup.
