I cannot delete the vault.
How can i copy, move, rename files or folders on Amazon Glacier?
Currently Amazon Glacier API doesn't support COPY operations. There is no way to copy/move/rename files or folders for now.
How can i verify that file was uploaded correctly?
When you upload the files, FastGlacier checks file integrity by calculating sha256 hash and sha256-tree-hash of an each part of the file and sha256-tree-hash of the entire file when completing the upload. If the hashes do not match, you will see corresponding error message and file will not be written.
Each time i try to download inventory from Amazon Glacier it fails.
Try to disable HTTPS in Tools, Options, Connection and request new inventory again.
I want to install FastGlacier on another computer. How can i transfer all metadata onto the new computer.
How does the Folder Comparison tool work?
If hashing is enabled, it uses the hashes to compare files. Glacier hashes are stored on Amazon Glacier and obtained from the inventory. Hashes for local files are calculated during comparison. If hashing is disabled, timestamps and file sizes are used to compare files.
I'm receiving OutOfMemoryException when trying to open the vault.
You may receive these errors when you are trying to open the vault containing very large amount of files. We recommend to split large backups to multiple vaults. Max files per vault depends on the memory installed on your machine. We recommend no more than 100,000 - 200,000 files per vault.
I'm receiving "ResourceNotFoundException: The upload ID was not found" when trying to resume upload.
Multipart uploads are valid for 24 hours. This means that if you try to resume your upload after 24 hours from the last upload request, you will receive ResourceNotFound errors.
There is no way to resume such uploads. You may try the following:
- Cancel failed uploads
- Wait 24 hours and request last inventory
- After receiving last inventory compare the folder or a vault with the local directory to find the files that were not uploaded (to compare the folders select the folder or a vault, right click and choose 'compare with local folder')
I'm receiving "System.IO.IOException:Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host." when trying to upload my files.
Usually these errors appear when you are trying to upload multiple files or parts using high number of concurrent uploading threads. Amazon Glacier server closes the connection: 'An existing connection was forcibly closed by the remote host'
You may try the following:
- Decrease the number of concurrent working threads, usually 8-10 threads are enough to use all available bandwidth, but in some cases you need to set it to 4-5, it depends on your bandwidth.
- Slightly decrease the send/receive buffer size in Tools, Options, Connection.
- Increase the number of retries on error and increase the delay between retries.
- Try to disable HTTPS in Tools, Options, Connection
- Try another region.
We uploaded about 100 GB of data. Our amazon report said that we had 19,000 requests, this was approximately $1. Where do they come from?
FastGlacier breaks large files into the parts and uploads them in parallel, this feature is called multi-part upload and it may greatly improve your uploading speed. Thereby uploading of 100 Mb file (with the part size set to 8 Mb) may generate about 15 requests: Initiate multi-part upload, upload each part, finish multi-part upload. To decrease the number of requests, you may try to increase the part size in Tools, Options, General.
