The cool thing about my bupsky script is it automatically backs up the whole tree of the current directory, even things called junk.jnk. I have 14TB disk space so I never thought about the cost of backing up temporary files, but this thread has made me realize that a simple script to delete all trees not containing a file less than X days old would lessen the temptation to not back up junk files. I'll show you something: [slitt@mydesk ~]$ du -hs /scratch/bup 48G /scratch/bup [slitt@mydesk ~]$ Consuming 48G with ancient backups that are already backed up by my main backup system is inexcuseable. Soon I'll need to write a program to tree delete all trees with no files under X days old. The big challenge will be to include barriers to prevent deletion of young files if my clock goes bad, and also to prevent deletion of random directories (like /home/slitt for instance) if something bogus happens. Thanks for the idea.

Hi,
After installing LyX, the backup directory is empty (Preferences >
Paths). Does that mean that no backups are created by default or that
the backups are created even though "Backup documents, every ...
minutes" is checked (Preferences > Look & Feel > Document Handling)
(btw. Look & Feel seems a misnomer for backup settings). Or is a
backup created in the directory of the lyx file (the title bar shows a
directory even for new not yet saved files, so I suppose these files
are backup there as well)?
Hi Daniel,
This isn't responsive to your exact question, but it still might be
helpful...
The way I've designed my workflow, backup is a multi-pronged strategy
not depending on any one application (such as LyX).
Obviously, one must regularly and frequently make complete backups of
all their data, data being stuff they can't reinstall or re-download.
This is the foundation of all backup.
But you can't do that every hour, or every 10 minutes when you're
working on a project. Git's pretty good for making backups every time a
milestone is reached (perhaps completion of another chapter). But git
isn't perfect: It takes an amount of time and concentration that could
cause you to forget what you were writing about.
I use a shellscript, called "bupsky", to back up at arbitrary moments
so I don't get knocked back more than a few minutes when working
continuously on a project. Here's bupsky:
==
#!/bin/sh
buptrunk=/scratch/bup
curdir=$(pwd | sed -e "s/.*\///")
bupdir=$buptrunk/$curdir
now=$(date +%Y%m%d_%H_%M_%S)
src=../$curdir
dst=$bupdir/${curdir}_$now
if test ! -d $bupdir; then
mkdir $bupdir
fi
cp -RpL $src $dst
echo backup written to $dst
==
The preceding shellscript takes the current directory and the whole
tree below it, can copies it. For instance, with my system, If I were
working in ~/docs/mynewbook, then bupsky would take that directory and
everything below it, and copy it to a directory something like
/scratch/bup/mynewbook_20210627_16_01_21 . The timestamp enables me to
roughly isolate *which* version is what I need. I'd anticipate bupsky
being good between git commits, or between real backups when git or
some other version control program isn't being used.
Bupsky isn't optimal for trees containing huge files. Then again,
backing up huge files in any way is suboptimal.
Obviously, bupsky will eventually fill the disk if things aren't
pruned. No problem, once every 2 weeks, run a program that searches
every directory under the backup root (/scratch/bup in my case), and rm
-rf on any tree not containing a file less than 8 days old, on the
theory that by that time, you will have backed up all your data and
don't need the bupsky-created directories anymore.
Like I said, this isn't responsive to your question, but might be handy.

Or is a backup created in the directory of the lyx file (the title bar shows a directory even for new not yet saved files, so I suppose these files are backup there as well)? Daniel From what I understand, backups are created iff a lyx file changes while edited by lyx. Kornel I still find LyX's backups a bit confusing. Officially it says in the User Guide: "Backup original documents when saving creates a backup copy of the file in the state when it was opened or when it was saved the last time. It is stored in the Backup directory (see section [sec:Paths]) or in the same folder as your document if no Backup directory is specified. The backup file has the file extension “.lyx~”. With the option Backup documents, every, you can specify the time between backup saves. Save documents compressed by default always saves files in a compressed format (see also section [subsec:Compressed]). This applies to newly created documents only. The compression status of existing documents is not changed when saving." Sometimes there is a backup with the ".lyx˜" extension but sometimes with the ".lyx#" extension (as in "#filename.lyx#"). Contrary to the Guide, it seems as if the latter is the backup created automatically every 5 minutes by default. Also, they are not strictly speaking created every 5 minutes but only if in addition the document is the active one on LyX. That does not seem very safe. Then I find the ".lyx~" files in my directories. I guess they are created when LyX crashes? And maybe also in the case that Kornel mentions, if I understood it correctly, i.e. when a document that is edited in LyX is changed (externally)? It's all a bit confusing to me. Why are there different file extensions/names? Why does it periodically backup only when the document is active? What happens when LyX crashes with documents that have never been saved? Are there any backups created? Daniel -- lyx-users mailing list lyx-users@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-users

Daniel My backup directory path is empty and LyX automatically creates backups in the document's directory. The backups have the extension .lyx~, so they are considered "hidden files" by Mint, Ubuntu and I suspect other Linux distros.
