it is a year and a half old 8 tb purple drive and this deleting of files takes forever
What is the block size that you formatted with?
scrolling down and selecting the files from a camera I want to delete while holding the shift key and then right click on that column and selecting deleteHow are you deleting? BI database management or direct delete by you?
If you're deleting for good, hold down the shift key when you click delete, then select permanently delete, If you don't permanently delete the files, they go into the Recycle Bin which may take longer. Depending on your computer, number of files, phase of the moon, etc. your results may vary.scrolling down and selecting the files from a camera I want to delete while holding the shift key and then right click on that column and selecting delete
I have always done it that way, I tried just letting it write over the older files but when I go to view alerts it gets really laggy and slow. I have the recordings set to 2 gb on the big cameras and one gig on the smaller camerasHmmm. Why are you doing it that way or are these exports? I can tell you that when I installed a new purple for video storage my original intent was to copy the files off the old drive and onto the new one. Even at SATA speeds that would have taken a few days to move 4TB of data. I ende up reformatting the old drive and starting fresh again instead. How big are the files, multi MB or multi GB?
thanks I will try shrinking the size of the recordings but with the 2 speed domes I usually run them at 25 or 30 fps becuase I really like the sharpness when seeing bears, coyotes or panthersI keep everything at one hour for both 2MP and 4MP cameras. That keeps the files sizes just under a GB for a 4MP camera, running 10240 bit rate at 15F/ps. 2MP cameras are in the 500MB range. Once you get past a GB any file operation, moving or deleting, is going to be slow. I've never had any slowness or lagginess playing back the full file or just an alert. I'll speculate fragmentation is the problem, but that is a guess at best.
Thank-you, updated my cams to use "&CAM\&CAM.%Y%m%d_%H%M%S"My Standard allocation post.
1) Do not use time (limit clip age)to determine when BI video files are moved or deleted, only use space. Using time wastes disk space.
2) If New and stored are on the same disk drive do not used stored, set the stored size to zero, set the new folder to delete, not move. All it does is waste CPU time and increase the number of disk writes. You can leave the stored folder on the drive just do not use it.
3) Never allocate over 90% of the total disk drive to BI. Leave at least 50GB free.
4) if using continuous recording on the BI camera settings, record tab, set the combine and cut video to 1 hour or 3 GB. Really big files are difficult to transfer.
5) it is recommend to NOT store video on an SSD (the C: drive).
6) Do not run the disk defragmenter on the video storage disk drives.
7) Do not run virus scanners on BI folders
8) an alternate way to allocate space on multiple drives is to assign different cameras to different drives, so there is no file movement between new and stored.
9) Never use an External USB drive for the NEW folder. Never use a network drive for the NEW folder.
10) for performance do not put more than about 10,000 files in a folder, the search and adding files will eat CPU and disk performance. Look at using a sub folder per camera (see &CAM in bi help)
Advanced storage:
If you are using a complete disk for large video file storage (BVR) continuous recording, I recommend formatting the disk, with a windows cluster size of 1024K (1 Megabyte). This is a increase from the 4K default. This will reduce the physical number of disk write, decrease the disk fragmentation, speed up access.
Hint:
On the Blue iris status (lighting bolt graph) clip storage tab, if there is any red on the bars you have a allocation problem. If there is no Green, you have no free space, this is bad.
Sorry have to stop you right there, I wish to clarify elements.thanks I will try shrinking the size of the recordings but with the 2 speed domes I usually run them at 25 or 30 fps becuase I really like the sharpness when seeing bears, coyotes or panthers
Manually deleting files is ridiculous. The entire point of a VMS is for it to do it for you. You need to figure out the underlying problem. Your database should be on an ssd and you should have a some free space on your recording drive so that it does not fill completely.I have always done it that way, I tried just letting it write over the older files but when I go to view alerts it gets really laggy and slow.
