Incremental Backup Files are HUGE
Hello,
I have been running TrueImage for a few months now in Incremental mode. The backups save to my networked NAS. It is running fine, but I am quickly running out of space on my NAS. Each incremental backup (daily) is at least 7 GB, sometimes as large as 14 GB +.
From what I understand, the incremental backup should only be backup up new files/data, correct? If this is the case then something is not right... I add maybe 500 MB of data per day, usually much less than that. So then shouldn't my incremental backup files be 500 MB or less on those types of days? Or am I misunderstanding things?
Thanks!
That's the thing... I'm not defragging or anything like that. I'm simply working (photoshop, dreamweaver, etc), going online, etc. Nothing huge. Hence my surprise when these backup files ended up being so huge.
Would a Differential backup give me smaller filesizes? Any disadvantages to going with Diff instead of Incremental?
I don't know that it would make any difference on this issue.
A task for Incremental or Differential will always begin with a full backup. That is necessary, as that becomes the baseline.
For an Incremental task, after the first full backup, subsequent backups will be incremental, each one based on changes since the previous Incremental backup, all the way back to the second backup being incremental based on changes since the full backup. As such, you need all links in the chain, all incremental backups right back to and including the first full backup, in order to Restore.
For an Differential task, after the first full backup, subsequent backups will be differential, each one based on changes since the first full backup. To restore, you would need just any Differential and the Full backup on which it is based.
You should not allow an incremental chain to become too long. An incremental restore depends upon every incremental in the chain being valid, including the original full. It's better to limit each chain to just a few incrementals, followed by a fresh full backup to start a new chain.
I have TI 2013 with Plus Pack and just received 5 new ST2000NM0033 drives (enterprise) to creat RAID 10 plus spare using SansDigital TR5UT+ using the mfg hardware controller card. The four drives are seen in Disk Management as a healthy partition (3725.81 GB NTFS). The floods in Thailand delayed geeting the drives to setup within the warranty period. There are identical disks (2TB). I want to set this RAID 10 unit with spare up to mirror internal SSD drive C using disk 1 and 2; then mirror internal drive D (2TB) using disk 3 and 4 which are all 2TB. Disk 5 will be a spare. WHAT DO I DO FIRST? Synchronization? Just go to Backup and Recovery, then Disk and Partitions? How do I mirror C: to disk 1 and 2 only, then mirror D: to disk 3 and 4 only.
Any help would be much appreciated. When I bought the software I never thought it would take so long to get these hard drives.
DellXPS8500, Windows 7 pro. I have a second Sans Digital Unit TR5UT+ as a JBOD using straight USB 3.0 without a controller card.
Thank you,

May be it performs sector-by-sector backup actually. It (or older versions were reported to) may switch to it silently even if it is not specified in options. Then it will include swap file as well and all removed temporaries.
ps - Richard, you may would like to empty your post here as you have created separate thread for your question.

Maybe it's your System Restore files that are causing the large sizes.
