轉到esim並連上網路了，開啟網頁卻又顯示無網路時，要去設定裡把這個esim的漫遊開啟才會開始連線。

如果切到esim後，網路一直不穩，可把手機重開試試。

檔案的檔名或路徑太長 無法移動

   環境:

windows

異常狀況:

有些檔案的路徑，連同檔名，非常的長，要複製/移至 其他資料夾，就會跳出錯誤，要重新命名，讓長度縮短，才能複製/移至 其他資料夾

解決過程:

如果檔案很多，改名稱太麻煩了，可用free file sync，這是檔案同步軟體，用它來把要移動的檔案同步到其他位置，就可以完成，不會因為路徑名稱太長而無法移動。

Environment:

Windows

Issue:

Some files have very long file paths, including the file names. When trying to copy or move these files to another folder, an error occurs.

The file or folder names must be renamed to shorten the overall path length before the files can be copied or moved successfully.

Troubleshooting and Resolution:

If there are many files, renaming them one by one can be time-consuming.

In this case, FreeFileSync can be used. It is a file synchronization tool that can synchronize the files to another location.

By using FreeFileSync to synchronize the files to the target location, the files can be transferred successfully without being blocked by the long file path issue.

excel存檔就當機

 環境:

2007，2010，2013，2016，m365 excel 

異常狀況:

同一個xlsx檔:

透過m365 excel 開啟後，存檔正常。

透過2007，2010，2013，2016 excel 開啟後正常，存檔的話excel程式就會當掉。

解決過程:

該檔案中，有附上幾個貼圖。

在m365 excel裡可正常看見圖，但在2007，2010，2013，2016 excel 中，看不到圖，只會看到#VALUE!

因為該圖是用m365裡的「圖片置於儲存格內」功能放入，這功能只有在 Microsoft 365  Office 2024，但在其他較舊的excel則不支援。

所以不但看不到圖，就算只是在其他欄位修改資料存檔，都會直接當掉。

Environment

• Microsoft Excel 2007

• Microsoft Excel 2010

• Microsoft Excel 2013

• Microsoft Excel 2016

• Microsoft 365 Excel

Issue

Opening the same .xlsx file shows different behavior depending on the Excel version.

• Microsoft 365 Excel: Opens and saves normally.

• Excel 2007/2010/2013/2016: Opens the file successfully, but Excel crashes when saving.

Investigation

The workbook contained several images.

• In Microsoft 365 Excel, the images displayed correctly.

• In Excel 2007/2010/2013/2016, the images did not appear and were shown as #VALUE! instead.

The cause was that the images had been inserted using the "Place in Cell" feature, which is only supported in Microsoft 365 and Office 2024.

Because older Excel versions do not support this feature, the workbook becomes incompatible. As a result, not only are the images displayed incorrectly, but even saving changes made in unrelated cells causes Excel to crash.

Resolution

The issue is caused by using the "Place in Cell" image feature, which is not compatible with Excel 2007/2010/2013/2016.

To make the workbook compatible with older versions, replace the "Place in Cell" images with standard inserted pictures before distributing the file. After removing or converting those images, the workbook can be opened and saved normally in older versions of Excel.

DELL idrac 擴充硬碟設定

 

  環境:

Dell server idrc

raid 5

設定過程:

為了增加容量，新增了硬碟。

插入硬碟後，在idrac內，要去"維護"--> "作業隊列"裡面，會出現待執行的工作，就可以看到插入的硬碟，要做何種設定，這邊就可以選擇要擴充到原本的raid中，設定好，這個作業不到幾分鐘就會完成了。。

完成後，在到"儲存"-->"虛擬硬碟"，這邊就可以看到目前的擴充進度。

Environment:

Dell Server
iDRAC
RAID 5

Procedure: Expanding a RAID 5 Virtual Disk

To increase the storage capacity of an existing RAID 5 array, install the new hard drive into the server.

After the drive is installed:

1. In iDRAC, go to Maintenance → Job Queue.
2. A pending job for the newly inserted drive will appear.
3. Select the appropriate operation to expand the existing RAID 5 virtual disk.
4. Apply the configuration.

The configuration job itself typically completes within a few minutes.

Monitoring the Expansion Progress:

After the job has been applied:

1. Go to Storage → Virtual Disks.
2. Select the RAID virtual disk.

You can monitor the RAID expansion (reconfiguration) progress from this page until the operation is complete.

Note: Although the configuration job completes quickly, the actual RAID expansion and background initialization may take several hours depending on the RAID controller, disk capacity, and system workload. During this time, the virtual disk remains available, but performance may be reduced until the expansion is finished.

Synology active backup for business 即時還原 虛擬機

  環境:

synology Active Backup for Business

透過"即時還原"功能 ，快速還原整台虛擬機

設定過程:

在Active Backup for Business備份的虛擬機，可以全部完整還原到esxi/hyperv主機上，因為要將所有資料還原回去，時間需要比較久。

但今天只要想要測試一下，可以在還原時，選擇"即時還原"。

這樣的話，還原是將synology掛載到esxi上變成一個datastore，所以還原過程不到幾分鐘就完成了。

可以馬上開始使用，但任何資料異動，會另外儲存，不會寫入虛擬機的vmdk中。

測試ok沒問題，就先關機，回到synology Active Backup for Business中，在還原工作裡找到剛剛的那個工作，選擇"取消"，這台虛擬機就會從esxi/hyperv上刪除，datastore也會被卸載，都不需要在esxi/hyperv上做刪除。

Environment:

Synology Active Backup for Business
Instant Restore of a Virtual Machine

Overview:

Active Backup for Business can fully restore a virtual machine to an ESXi or Hyper-V host. Since the entire VM and all of its data must be copied back, a full restore can take a considerable amount of time.

If you only need to quickly test or verify a backup, you can use the Instant Restore feature instead.

How Instant Restore Works:

1. In Active Backup for Business, select the virtual machine and choose Instant Restore.
2. During the restore process, Synology mounts the backup repository to the ESXi or Hyper-V host as a datastore.
3. Because the VM runs directly from the backup storage, the restore process typically completes within a few minutes.
4. The virtual machine can be powered on and used immediately.

Any changes made while the VM is running are stored separately and are not written back to the original VMDK files.

Cleanup After Testing:

Once testing is complete:

1. Shut down the virtual machine.
2. Return to Active Backup for Business.
3. Open the Restore Tasks list.
4. Locate the Instant Restore task and select Cancel.

Active Backup for Business will automatically:

• Remove the virtual machine from the ESXi/Hyper-V host.
• Unmount the temporary datastore.

No manual cleanup is required on the ESXi or Hyper-V host.

synology Active Backup for Business虛擬機備份後 只還原特定檔案

 環境:

synology Active Backup for Business

備份整台虛擬機

異常狀況:

需要還原特定檔案，但不想花時間先還原整台虛擬機

解決過程:

在Active Backup for Business的確是只有整台虛擬機還原的選項。

但可以到Active Backup for Business Portal 裡面，在左上角可以選擇你備份的其中一台虛擬機。

畫面下方就會有時間軸讓你選擇備份的時間點，畫面中間就是每個磁區，你就可以點進去查看裡面所有的檔案，針對需要還原的檔案直接下載到本機中就行了。

Environment:

Synology Active Backup for Business

Virtual Machine Backup

Issue:

You need to restore specific files from a virtual machine backup, but you do not want to spend the time restoring the entire virtual machine first.

Resolution:

Although Active Backup for Business only provides an option to restore the entire virtual machine, you can restore individual files through Active Backup for Business Portal.

1. Open Active Backup for Business Portal.
2. In the upper-left corner, select the backed-up virtual machine.
3. Use the timeline at the bottom of the page to choose the desired backup point.
4. The center pane will display all the virtual disks.
5. Browse the disks to locate the required files or folders.
6. Download the selected files directly to your local computer.

This method allows you to restore individual files without having to restore the entire virtual machine first, saving both time and storage space.

AD匯入admx

 AD裡GPO有些設定不在內建的選單中，但可以透過下載admx檔，增加要透過GPO派送的設定。

以m365 office為例，可以先去下載它的admx檔(https://www.microsoft.com/en-us/download/details.aspx?id=49030)。

下載的時後雖然只有英文版，但下載完，執行後，會將相關的檔案解壓縮在一個資料夾中。

裡面會有admx跟adml檔。
