TrueImage 7.0 looks good; Incremental creates 2nd file bigger then first?
Acronis True Image seems to be a great product. Thanks for the
suggestion in the other thread. I have been evaluating TrueImage 7.0 and have created and restored a few images. (I love the image creation of an online system/OS partition without having to reboot!) I've also done an incremental image backup, and I find that TrueImage 7.0 creates a second file that's slightly larger than the first. I'm left to wonder: What's the point of my incremental backup if it's going to more-than-double my backup storage size? If that's the case, why not run a separate, full backup? It's also unclear as to whether or not I restore with the original backup .tib file (and I'm putting the backups all in one file, fyi) or the newly-created one. I seem to have trouble executing a restore with the new one. However, this point is minor if the above point is not addressed, because I won't run an incremental if it doubles my backup-storage size and will instead just run a new, full backup every time. I would, however, REALLY like to be able to generate incremental image backups that make my backup store not any larger then the delta/changes that actually occur in the partition. Isn't this the point of incremental backups in the first place? (I'm posting this here as well as sending question to Acronis support. I bet I get answers more quickly from here than Acronis. Thanks for any help Matt -- Remove the obvious text (including the dash) to email me. |

First, make sure you're running the latest version. Build 582 is the latest, and I can't say one way or another if the previous version behaved the same way. (I have not tried it) When you create an incremental backup, you first select which TIB you are going to "base" your incremental backup off of. When you create an image, you select an existing file as the target. Then it will prompt you if you want to create an incremental backup. TrueImage will create a new file with an incrementing number after that first file that contains only changed files since the last backup. For example, I have a job scheduled to create a full backup on the 15th of every month. It's set with a max file size of 1.9GB (To fit on an ISO DVD), and it created these files: (TrueImage automatically appends the number after the file names) Foo_C_15th1.tib 1.9GB 3:17AM Foo_C_15th2.tib 0.8GB 3:21AM Just now I tested doing an incremental backup, using the first TIB above as the "base" of it. (Though I'm sure either file would work). It created an additional file: Foo_C_15th1.tib 0.1GB 11:39PM The first two files were not modified in any way. When I did the incremental backup, it only added the files which are new or have changed since the last backup. It's also unclear as to whether or not I restore with the original backup .tib file (and I'm putting the backups all in one file, fyi) or the newly-created one. You can restore using any of the files. TrueImage will detect that they are all part of the same set. When you go to restore, it will prompt you for which date you would like to restore to (The date of the original backup, or the date of any of the subsequent incremental backups). VERY cool feature. I would, however, REALLY like to be able to generate incremental image backups that make my backup store not any larger then the delta/changes that actually occur in the partition. Isn't this the point of incremental backups in the first place? Yes, that's exactly the point. Perhaps you missed a step in the procedure, such as selecting an existing TIB file when it asks you for the target? -WD |
