Limiting Google Drive upload & synchronisation speeds using Trickle
9th October 2021Having had a mishap that lost me some photos in the early days of my dalliance with digital photography, I have been far more careful since then and that now applies to other files as well. Doing regular backups is a must that you find reiterated by many different authors, and the current computing climate makes doing that more vital than it ever was.
So, as well as having various local backups, I also have remote ones in the form of OneDrive, Dropbox and Google Drive. While these more correctly are file synchronisation services, disciplined use can make them useful as additional storage facilities in the interests of maintaining added resilience. There also are dedicated backup services that I have seen reviewed in the likes of PC Pro magazine, but I have to make use of those.
Insync
Part of my process for dealing with new digital photo files is to back them up to Google Drive, and I did that with a Windows client in the early days but then moved to Insync running on Linux Mint. One drawback to the approach is that this hogs the upload bandwidth of an internet connection that has yet to move to fibre from copper cabling. While having fibre connections to a local cabinet helps, a 100 KiB/s upload speed is easily overwhelmed and digital photo file sizes keep increasing. It does not help that I insist on using more flexible raw formats like DNG, CR2 or CR3 either.
While making fewer images could help to cut the load, I still come away from an excursion with many files because I get so besotted with my surroundings. This means that upload sessions take numerous hours and can extend across calendar days. Ultimately, this makes my internet connection far less usable; hence I want to throttle upload speed, much like what is possible in the Transmission BitTorrent client or in the Dropbox client. Since this is not available in Insync, I have tried using the trickle command instead, and an example is below:
trickle -d 2000 -u 50 insync
Here, the upload speed is limited to 50 KiB/s while the download speed is limited to 2000 KiB/s. In my case, the latter of these hardly matters, while the former leaves me with acceptable internet usability. Insync does not work smoothly with this, though, so occasional restarts are needed to keep file uploads progressing and CPU load also is higher. As rough as the user experience feels, uploads can continue in parallel with other work.
gdrive
One other option that I am exploring is the use of the command-line tool gdrive and this appears to work well with trickle. After downloading and installing the tool, getting going is a matter of issuing the following command and following the instructions:
gdrive about
On web servers, I even have the tool backing up things to Google Drive on a scheduled basis. Because of a Google Drive limitation that I have encountered not only with gdrive but also with Insync and Google's own Windows Google Drive client, synchronisation only happens with two new folders, one local and the other remote. Handily, gdrive supports the usual bash style commands for working with remote directories, so something like the following will create a directory on Google Drive:
gdrive mkdir ttdc [ID for parent folder]
Here, the ID for the parent folder may be omitted, though it can be obtained by going to Google Drive online and getting a link location by right-clicking on a folder and choosing the appropriate context menu item. This gets you something like the following and the required identifier is found between the last slash and the first question mark in the address string (so as not to share any real links, I made the address more general below):
https://drive.google.com/drive/folders/[remote folder ID]?usp=sharing
Then, synchronisation uses a command like the following:
gdrive sync upload [local folder or file path] [remote folder ID]
There also is the option to do a one-way upload, and this is the form of the command used:
gdrive upload [local folder or file path] -p [remote folder ID]
Because every file or folder object has its own ID on Google Drive, it is possible to create two objects on there that appear to have the same name, though that is sure to cause confusion even if you know what is happening. It is possible in each of the above to throttle them using trickle as well:
trickle -d 2000 -u 50 gdrive sync upload [local folder or file path] [remote folder ID]
trickle -d 2000 -u 50 gdrive upload [local folder or file path] -p [remote folder ID]
Handily, this works without the added drama seen with Insync and lends itself to scripting as well, so it could be something that I will incorporate into my current workflow. One thing that needs to be watched is file upload failures, but there may be ways to catch those and retry them, which would be another thing that needs doing. This is built into Insync, and it would be a learning opportunity if I were to stick with gdrive instead.
A collection of legal BitTorrent sites
19th October 2014It was an article in a magazine that revealed these legal BitTorrent download sites to me, so I thought that I'd keep them on file for future reference while also sharing them with others who might need them. As far as I am aware, they are all legal in that no copyrighted material is on there. If that changes, I am happy to know and make amendments as needed.
My own interest in torrents arises from their being a convenient way to download installation disk images for Linux distributions, and at least one of the entries is devoted to just that. However, the distribution also lends itself to movies along with music and books, so that is reflected below too. Regarding downloading actual multimedia content, there is so much illegal downloading that a list like this is needed and has blackened the reputation of BitTorrent too because it only ever was conceived as a means for distributing large files in a peer-to-peer manner without the use of a single server. Of course, any use can be found for a technology, and it never has to be legal or morally acceptable either.
Removing advertisements from uTorrent
12th July 2014BitTorrent may have got some bad press due to its use for downloading copyrighted material such as music and movies, but it does have its legitimate uses too. In my case, many a Linux distro has been downloaded in this way, and it does take the weight off servers by distributing the load across users instead.
Speaking of Linux, my general choice of client has been Transmission and there are others. In the Windows world, there is a selection that includes BitTorrent, Inc. themselves. However, many favour uTorrent (or μTorrent) so that's the one that I tried and there are free and subscription-based options. To me, the latter feels like overkill when an eternal licence could be made available as an easy way to dispatch the advertisements on display in the free version.
As much as I appreciate the need for ads to provide revenue to a provider of otherwise free software, they do need to be tasteful and those in uTorrent often were for dating websites that had no scruples about exposing folk to images that were unsuitable for a work setting. Those for gaming websites were more tolerable in comparison. With the non-availability of an eternal licence option, I was left pondering alternatives like qBittorrent instead. That is Free Software too, so it does have that added advantage.
However, I uncovered an article on Lifehacker that sorted my problem with uTorrent. The trick is to go into Options > Preferences via the menus and then go to the Advanced section in the dialogue box that appears. In there, go looking for each of the following options and set each one to false in turn:
offers.left_rail_offer_enabled/left_rail_offergui.show_plus_upselloffers.sponsored_torrent_offer_enabled/sponsored_torrent_offer_enabledbt.enable_pulsegui.show_notorrents_nodeoffers.content_offer_autoexec
In practice, I found some of the above already set to false and another missing, though setting those that remained from true to false cleaned up the interface, so I hope never to glimpse those unsuitable ads again. The maker of uTorrent needs to look at the issue or revenue could get lost, and prospective users could see the operation as being cheapened by what is displayed. As for me, I am happy to have gained something in the way of control.
