Some thoughts to the WebUI

Will it search through all connected drives? So in case of a letter swap, will it find the correct drive? Will the user be informed in case of error?

This makes the usage very complicated. in this case I could also use the cli version which is free for personal use. The webui should target users who want an easy to configure backup solution. The webui is very very close to it and it would be sad if it will fail only because missed backups can not be addressed.

idk :-/ (i wouldn’t expect it to, though)

I hope so. (idk either)

I’m not a web-ui user, so all i’m saying here is from what i read in other posts and what i know from my cli usage.

I only see a notification option via mail but only in scheduled jobs. I do not want to be informed every hour about an successful backup.
perhaps @gchen can comment on this :slight_smile:

edit: Video finished:

No, of course not (@gchen, correct me if I’m wrong). It only looks at the storage path, i.e. only the drive letter under which the drive was originally registered. If the path doesn’t exist or if it doesn’t find the config file, I suppose ot will exit with an error, just like it will if your trying to backup to any other unavailable destination.

Great! Would you like to post it in a separate topic?

Since we’re pinging Gilbert anyway, I’d like him to confirm how duplicacy is supposed to be pronounced according to him. In my mind, the - acy is pronounced as in privacy. So that would put the emphasis on the syllable pli in duplicacy, but in some versions of English perhaps it’s also possible to ephasize the du. I’m not a native speaker…

my speaker used both versions in the video :smiley:
But me and the speaker are also not native (as you may have already guessed :wink: )
Would be nice to get the hint from @gchen

yes give me a second

edit:
@Christoph

feel free to change the category if I got it wrong

Yes, the email after each completed schedule is the only notification.

That is correct.

I’m not a native speaker either, so I really don’t know which syllable should be stressed. Maybe someone here can recommend an official pronunciation?

Did you mean http://healthchecks.io ? Without the ‘s’ it takes you to a domain reseller. However this is a cool idea! I was thinking of using email filters and maybe IFTTT, but that wouldn’t really help with missed backups. The Crashplan service has a tendency to stop working or not restart occasionally and it takes the “no backup” email for X days before I realize it.

Yes, sorry, fixed it.

This would make it a show stopper for me for windows.
Users must be informed if something is going wrong :wink:

Why not using the same methoed as duplicati does? Drive letter is really a bad idea in windows and if the user does not gets informed in case of an error… this is a receipe for desaster :scream:

This is not as easy as it sounds.

In fact, literally just this second, I checked the Duplicacy web edition icon in the tray next to the clock. Hovered over the icon and it disappeared. Duplicacy, was in fact, not running.

This is an issue I’ve been seeing for the past several weeks but am unable to put a finger on it. My PC is on 24/7 and I leave it logged in. Once a week or two I’ll notice Duplicacy isn’t running. Why? I have no idea! The Windows event logs don’t show any crashes. My last successful backup today was at 12:15 but the 14:15 (and 16:15 & 18:15) backup didn’t run according to the dashboard. Sometimes a day or two will pass before I notice it isn’t running. Luckily, today I only missed a few hours.

Anyway, the point I’m trying to make… Duplicacy itself can’t tell you if something like that goes wrong, if it isn’t even running. :slight_smile:

Hence the purpose of an external service like healthchecks.io. I recently set up an alert for a customer’s system running Vertical Backup (Duplicacy’s brother for ESXi hosts) and set up a pre-script to ping a given URL. If it doesn’t run, I get an email notification. I may have to do the same on my personal machine.

This is not my point. If a program crashes it can not alert the user this is clear. But if the backup medium is missing the user should be alerted. There is an easy solution to this. What do you think of a threshold which can be user defined. This threshold should check for the last successful backup and measure the time which has past since then. If the value is too high it should send a mail.
This would also help if duplicacy crashes entirely. At the next start a mail could be triggered that the last Backup is too old.

I like this idea and I definitely think notifications could be more finer grained.

I could try to write a script but for that I would need a time stamp format which can be set in relation to the actual time. Any ideas how to do this?

Normally when the web GUI crashes it will leave the stack trace in the ~/.duplicacy-web/logs/duplicacy_web.log. If you can’t find anything there maybe you can try ProcDump? This page has instructions on how to do that for a Windows service but it should work the same way for the web GUI:

2 posts were merged into an existing topic: How to pronounce duplicacy?

Thanks for that.

Looks like I’ll give ProcDump a go.

The duplicacy_web.log doesn’t show anything untoward, but the last section of the log when I last saw Duplicacy had crashed, only showed this:

2019/06/11 12:16:23 Schedule Regular next run time: 2019-0611 14:15
2019/06/11 14:15:01 Starting schedule Regular at scheduled time 2019-0611 14:15
2019/06/11 14:15:01 Created log file C:\Users\Droolio/.duplicacy-web/logs/backup-20190611-141501.log
2019/06/11 14:15:01 Running C:\Users\Droolio/.duplicacy-web/bin/duplicacy_win_x64_2.2.1.exe [-log backup -storage NAS -vss -stats]
2019/06/11 14:15:01 Set current working directory to C:\Users\Droolio/.duplicacy-web/repositories/localhost/0
2019/06/11 18:53:38 Duplicacy CLI 2.2.1

So it’s missing the ‘Created log file’, ‘Running’, ‘Set current working directory’ for repo ‘0’, plus the same for repo’s 1, 2 and 3 plus a final ‘Schedule Regular next run time’ - all missing. Seems to be crashing when trying to run the first job in the schedule.

I’ll try out ProcDump.

Instead of having to deal with https://healthchecks.io it would be great if this was a service that Duplicacy offered as part of the yearly license fee. If Duplicacy has not received a backup ping in 1-3 days they would send you an email. It wouldn’t need to support the CLI version since that is free, but it should be supported out of the box for Web.

Welcome to the forum!, “2” !
Personally I do not think it would be a good idea for the developer to split his resources to make what is essentially a completely new project.

But it might be might be possible to provide a option to send a report to one of the services that already exist. Some are free for personal use, and some might work better for commercial users.

We have already discussed https://healthchecks.io in other posts.
Another service is https://www.duplicati-monitoring.com, which as the name implies, is designed for Duplicati users, but they will not shun other users. (I use both)

I wanted to check the conditions for using this in my own (Duplicacy) scripts so I took the liberty of contacting the vendor mittelstandsoptimierer.de

@gchen, I got this reply from the devolpers of https://www.duplicati-monitoring.com

I don’t know how this fits in your plans for the GUI/CLI, but I imagine it could be possible to use this to provide backup monitoring and some statistics which some users might want.

This would be one way to achieve this without users having to script too much.

(And if CLI could have an option to write a JSON report, CLI users could also use it)

Subject: About Monitoring service for Duplicati - Will it allow other backup products?

Hi,

thank you for your email.

1. Do Mittelstandsoptimierer have plans to create a similar site for Duplicacy? (and would it be free for personal use?)

There is no definitive plan but we may do so. Of course we would appreciate if you could help us. Do you know any options in Duplicacy to get the backup reports? HTTP? Mails?
I guess a monitoring service for Duplicacy would also be donation-based.

2. If not, could it be allowed for Duplicacy users to use Duplicati-Monitoring?
(I could possibly write a script to deliver Duplicacy data in Duplicati-like
format)

Yes, you can use our service with any backup software or script that is compatible. We see that some people already use other software and we have no intentions to stop them. For example, somebody seems to be using Arq backup (https://www.arqbackup.com/) with our service.
But of course we cannot guarantuee that our service will keep working with other software that we don’t officially support.

3. If this is something you are considering, I could request the Duplicacy developer to add a feature for sending a http report for Duplicacy much like Duplicati does. (The format would be different but well defined)

That would be perfect, then it would be not a big deal to adjust or service.

[…]

If Duplicacy does not implement something that is Duplicati-compatible, I would prefer if it would export the data as JSON over HTTP. What Duplicati does looks like JSON, but is not exactly JSON, and thus is not that parser-friendly. Also, I would prefer if time-values would be UNIX timestamps.

Greetings,
Christopher

@akvarius I didn’t know duplicati-monitoring.com can support other tools. This is an interesting option and I’ll definitely look into how to generate those required JSON data.
