![]() ![]() These incrementals are fundamental to restoring the server to that specific point in time and therefore we can’t do anything about them per se. It can be that you will get a few Gigabytes of changes in a short period of time. We have Image based backup software that can snapshot the changes made in the last 15 minutes – if there is a program such as WFBS that makes large amounts of disk change in that 15 minutes then the incremental image will be quite a bit larger than normal. Ok – let’s tie this all together now to see the ramifications. Factors such as limited internet bandwidth really come into play here. This however relies on the incrementals being able to be small enough that they can be pushed out quickly to the remote location. This is a cool feature because it means as soon as an incremental image is created, it can be shipped offsite quickly and efficiently. Now if we look at one of the features of StorageCraft ImageManager called replication – this replication feature allows the incremental images to be sent over a LAN/WAN to another server or via FTP to a remote server. ShadowProtect takes these as incrementals and then ImageManager consolidates these based on various settings. Windows / SBS Backup automatically consolidates these into it’s backup file which is a VHD. The way these work is to take a base image one time only and then take some form of incremental backup from that point forward. This is great from a disaster recovery perspective as it allows you to minimise the data lost due to a system failure to a very small time window. This article talks about why that happens and shows how to avoid it.Īny image based backup software such as SBS 2008/SBS2011 inbuilt backup, or third party backup programs such as StorageCraft ShadowProtect have the ability to backup very fast and multiple times a day – as much as every 15 minutes in the case of ShadowProtect. However if you backup more often than that you might run into a problem with having very large incremental backups. In itself this is not a problem because a backup taken once a day with your favourite backup program will only record the differences between that point in time and the last backup which is fairly small. ![]() ![]() The disk activity is really a reorganisation of the pattern files and the database itself and is not actually an increase in the amount of data being stored. This combined with other architecture changes means that there is quite a lot of disk activity and change at certain times during the day. And a user told me, that Trend Micro is aware of this issue.Īddendum 2: It seems that we are one year out of support – from June 22, 2021, Trend Micro ends support for Windows 7 SP1 and Windows Server 2022.In Trend Micro Worry-Free Business Security 6.0 and higher, Trend have implemented new technology that reduces the size of pattern files distributed to the client machines. Anyone else who can report similar observations?Īddendum: My German readers told me in comments, that they was able to start Windows 7 in safe mode – then they was able to uninstall Apex (others disabled TM services). ![]() Since then many readers confirmed that issue, also on embedded clients, and it affects 32 and 64 bit systems. What all computers have in common so far is that they are still running Windows 7 and TrendMicro (various editions) is installed as the virus scanner.Īre there any findings from other readers? Ticket at TrendMicro is opened. just contacted me by mail and writes:Ĭurrently we have the problem with at least 15 customers that shortly after login the message "Critical error, the system will restart in 1 minute" appears on the computer and then the computer actually restarts. I myself can't find any problems with my Windows 7 SP1 with ESU at the moment, the system runs since hours without any problems. Affected are 32- and 64-bit Windows 7 clients (including embedded), and in all cases Trend Micro seems to be involved as the security solution. After I published the initial blog post in German, I receivedseveral reports from various users that there are problems with Windows 7 restarts because a critical error has occurred. ![]()
