Disk Cleanup
Demarcus Smith
Disk Clean-up (cleanmgr.exe) is a computer maintenance utility included in Microsoft Windows designed to free up disk space on a computer's hard drive. It was introduced in Windows 98, but has now been deprecated and replaced with a modern version in the Settings app, although it still exists as a legacy tool in Windows.
The utility searches files that are no longer of any use, and then removes the selected unnecessary files. There are a number of different file categories that Disk Clean-up targets when performing the initial disk analysis:
Aside from removing unnecessary files, users also have the option of compressing files that have not been accessed over a set period of time. This option provides a systematic compression scheme. Infrequently accessed files are compressed to free up disk space while leaving the frequently used files uncompressed for faster read/write access times. If after file compression, a user wishes to access a compressed file, the access times may be increased and vary from system to system.
If you're just looking to free up disk space, consider using Azure File Sync with cloud tiering enabled. This method lets you cache your most frequently accessed files locally and tier your least frequently accessed files to the cloud, saving local storage space while maintaining performance. For more information, see Planning for an Azure File Sync deployment.
Hans Petter, when you see this message, what are you cleaning up? As Sachin suggested, try df -h to see where to look, and then use du -shx * on the implicated sub-directories. Is that where you've been cleaning up? If you really do have a 290GB data disk, I can't imagine what would be gobbling over 10GB per day.
If that is a common problem, that your data disk has a high grow rate you might want to check Bob's shell command from here: -threat-management/f/web-protection-web-filtering-application-visibility-control/46820/high-bandwidth-usage/326989#326989
Disk Cleanup searches your disk and then shows you temporary files, Internet cache files, and unnecessary program files that you can safely delete. You can direct Disk Cleanup to delete some or all of those files. This tool guides you through a series of tasks and systematic procedures to help you get back to work quickly.
However, I was wondering where the 'tools' are. Things like a 'disk cleanup' or defrag program. I know my MacBook doesn't need any maintenance right away as I've only just got it, but its nice to know where these things are for future reference.
I'll just add to the good advice you have gotten so far. If your MBA has a solid state drive the drive firmware itself does "cleanup." Every time you save a file it is moved to a new location. Solid State drives do not have sectors in the usual sense, so there is nothing to clean up. In addition, software that overwrites deleted files ("secure erase") won't work on an SSD, because the location of the deleted storage is unknown. Which means, if you want secure erase you should encrypt your drive using the built in File Vault feature (System Preferences->Security & Privacy).
This is not the first time this happens to me and every time it is an issue since it fills up the disk and it wont release the space until (at least) I either reboot the media agent or add a advsetting key (CLEANUP_TEMP_DB_DAYS = 0). In this case, particular case, i have done both and still wont release the space.
Long story short, any time I request a browse from a job that is available on disk but is fairly old, the media agent kicks off a Index Restore, since those indexes are not on media agent anymore. The index kicks in, and thats when the operation starts to fill up the disk. (always with NDMP (V2) that are massive).
Thanks for the reply @Jon Kuzmick I`m not quite sure I follow. The index restore to my understanding was only kicked off because of a attempt to restore a file from a NDMP client. Since I actually did not restore anything, in fact I cancelled the browse attempt, the index restore kept going until it filled up the disk. So this is not a backup operation that is filling up the disk, in fact I had 900GB before the restore attempt. I can not think that in a matter of few hours because of a cancelled restore operation my Index cache filled almost 1TB and there is no way to claim that space back. Again Ive had this issue in the past as I mentioned and the key had helped, but this time it didnt.
V2 should be keeping the full index on disk for the entire dataset. It should not be doing index restores unless it is damaged. The initial implementation always kept the index for jobs still in retention - I do not believe that changed, but I have been out of the game for a bit so it is possible.
Yes. The actual problem is a lot deeper than that and I actually think it should be reviewed by Dev. Basically whena Browse/Restore is kicked off (in my case on a NDMP) since my client has a huge index, the browse/restore has to reconstruct the index for that client which was well over 1.4TB (1.4TB being the free space on my index cache) not enough. So causing the media agent to fill up the entire index cache disk.
During that process for the workflow it also requires the rebuild a certain number of cycles which then led me to fill up the disk once again and never completed the workflow. So then the drilling down to the folder again that was filling up. Paused all services on the MA, deleted the folder again, run the Qcommand mentioned by @Mike Struening and re-run the workflow so it could complete the remaining subclients.
I hope this can help other users, but that Commvault also improves the way Index Reconstruction works because that is a complicated way to deal with an problem that could have been solved by the software understanding there is no more disk space therefore abort the task and errors out the browse/restore and delete the temp recon db created regaining the space utilizaded. Perhaps an error message with an article.
Hi I installed sentry on-premise using the docker compose script a few months ago and now my disk is almost full.
The version of Sentry I am currently running is Sentry 20.10.0.dev0 bdad080 and it is running on a Ubuntu 18.04 Server system.
This Remote Action is designed to help employees to maintain healthy levels of disk space. It can be used in 2 different formats, either with the Campaign which will provide some information to the employee with the option of a light or deep clean, which the employee can select. Without the campaign, administrators can use the Remote Action to automatically clean the disk according to the input parameter options they supply (Light or Deep).
All files inside user temporary folder (%TEMP%) whose last write time is older than 'remove_files_not_modified_in_days' input parameter, will be removed if deep cleanup option is selected in the campaign. Parameter 'maximum_delay_in_seconds' can be used to add random script execution delay. It should be used in virtualized environments to spread over time number of I/O requests on server hosting virtual machines.
Parameter 'MaximumDelayInSeconds' can be used to add random script execution delay. It should be used in virtualized environments to spread over time number of I/O requests on server hosting virtual machines.
SCCM cache cleanup does not work with Configuration Manager older than 2012.
The freed space shown in CleanupSpace output is calculated by accessing the 'FreeSpace' property of the Win32_Volume WMI Class before and after the execution.
Please consider this output as an orientation. It may be inaccurate or report 0 in certain situations due to the fact that external applications or services could be occupying the free space by downloading, creating or unzipping files.
This Remote Action helps to conserve disk space on end-user devices by performing a proactive recycle bin clean (compatible on Windows or macOS) with an optional capability to use a Campaign to request user permission.
In Windows 7, Vista, and XP, DiskCleanup frees disk space by cleaning areas that gather unneededfiles. Using Disk Cleanup regularly, along with ScanDisk,DEFRAG, and up-to-date virus patterns, will help keep yourcomputer running smoothly.
I have a laptop with Windows 11 Pro 21H2, upgraded from Windows 10 Pro. For a couple of weeks now disk cleanup does not work at all. Never had a problem before. The non-functioning seems to have started after I installed July updates at the end of July.
Using the instructions for removing the temp files manually, I was able to remove the temp files. But the others remained , especially the 2.28GB windows update cleanup files, which are the primary ones I wanted to clean up.
I prefer DISM++ over all those previously mentioned but @geekdom has supplied the first two steps to recovery in using the proprietory MSFT disk cleaner.
@OP you could also lookup sageset/sagerun switches for Disk Cleaner which opens up a lot more options to remove excess ?
If SLP duplications have not completed successfully, NBU will assign INFINITY retention to the images until the duplication has completed. Only then does SLP retention and expiration kick in.
Image cleanup can therefore only take place after successful duplication and image expiration.
When things go wrong either by calling sysprep.exe directly or via VMWare, its not immediately obvious what the error is. In fact I would say that it is immediately very confusing...and even worse sometimes it is not immediate at all. I wrote a post six months ago about how to troubleshoot unattended windows provisioning gone wrong. Here I want to look specifically at issues concerning disk cleanup.
There are a few techniques that can be applied here and which ones will depend on the version of windows you are running. I'm focusing here on the latest released server version 2012 R2. I'd definitely encourage you to read my vagrant post that talks about some of the new features of component cleanup and features on demand that can shave many gigabytes off of your base image. Another tool that many use to purge useless files from their windows os is cleanmgr.exe. Many know this better as the little app that is launched from the "disk cleanup" button when viewing a disk's properties.
