Is there an undo feature?

[AnnieQuinn]

Hello, I'm not good at digging into the features in Calibre. So, I'd like to ask everyone if there is an "undo" feature for bulk actions? If it exists, please help me.
For example: When editing information of multiple books at the same time, such as adding tags, removing tags.
The reason for this question is because I was planning to remove tag A for the books, but while I was sleepy, I clicked on tag B, because I didn't type the full word but only typed the first character and clicked to select, so I selected the wrong one.
And so, a bunch of books were mistakenly deleted by one tag. And maybe I have to go back to each book to add back the necessary tag that was mistakenly deleted.
Thanks for reading. ^^

In the past I tried the Audit Log plugin just in case I needed to undo bulk (the one time I tried, I couldn't figure how to proceed, or gave up because found another way, perhaps..), but eventually I switched to just doing metadata backups before doing something risky.

And as a rule of thumb I prefer to never do such operations when I'm sleepy ^^

Yes, I made a silly mistake. First time stumbling. Hahaa. I wouldn't say I was sleepy, more precisely, I was careless. How annoying, one second mistake, takes a whole day to fix.

@AnnieQuinn - I moved your issue to a separate thread, because it had nothing to do with Templates.

I don't have anything to add to what @Comfy.n posted. I avoid use of 'autocomplete' features - too dangerous for me (broken hands), if I can I turn them off.

AFAIK the revert doesn't work because of an error. It also badly bloats the DB.

I remember I made my mind to uninstall it after you commented something along those lines.

(BTW thanks also for having brought my interest in the template tester, this has encouraged me to try and understand some basics of GPM)

This is the script I run on Windows when I sense some imminent risk before bulk library operations:

PHP Code:

 @echo off
 
 Title Calibre Metadata Backup
 
 echo [93mRunning Calibre Metadata Backup... 
 
@echo off

set dt="%date:~-4,4%-%date:~-7,2%-%date:~-10,2%,%time:~0,2%_%time:~3,2%_%time:~6,2%"
set file=c:\mylib\metadata.db
set target=%UserProfile%\Documents\metadata-bck.db

copy /Y %file% %target% 

cd %UserProfile%\Documents 
"c:\Program Files\7-zip\7z.exe" a  -mx=1 metadata-%dt%.7z metadata-bck.db 

del metadata-bck.db
echo [44mMetadata Backup done. File is located in %target%.[0m

pause 


Notes:

• must have 7-zip installed and install path set accordingly. In my Calibre Config backup script, I use Windows built-in tar command, but for some reason I've chosen 7-zip to do metadata.db backups.
  
• must change the library path at line "set file=". I suspect that if the library path contains spaces, it should be quoted, but haven't tested.
  
• Compression levels may be set to the following:

-mx0 = Don't compress at all - just copy the contents to archive.
-mx1 = Consumes least time, but compression is low.
-mx3 = Better than -mx1.
-mx5 = This is default (compression is normal).
-mx7 = Maximum compression.
-mx9 = Ultra compression.

• I've set the backup path to Documents because that's a folder I use all the time so i can delete unneeded backups as soon as I spot them.
