File archiving tar find for files that are current

[Belinda Dermody]

Is there a way that I can use a combination of sh commands to archive files that were created less than 24 hours ago. I have a bunch of indexs that are updated using networker(I have 60 days worth) and I would like to archive the current ones after the nightly backup. The whole directly is 18gig and I would like once in a while just to do the current ones which would only take a few minutes instead of 4 hours. Using the find command looks like it uses the 24 hour break and these indexs are created around 2:30 AM and I would back them up around 7AM each morning.

James,

You can use the touch command to create a reference file with a specifed date and time. Then you can use find with -newer option to find the files more recent than the reference file.

Prepare a cron job that will create a file at 02:30AM. Then you can use find command with -newer option to get the list of the files that are created after that.

Pete thanks for you response, I tried it but here is my results. Although I touched a file named refffile with 1 minute past midnight, the find command comes back with all the files.

Hi,

find . -newer reffile -type f -exec ls -l {} \; |more

James,

I tried it as well and noticed some inconsistent results unless I restricted it to just files with -type f (as Robert-Jan suggested). Try that and see what you get!

You have to be careful with find and ls. If the result of the find command is a *directory* then you will do an 'ls -l dirname' which will list all files in that directory which is not necessarily what you want.

A couple of ways around this are: 1) use the '-type f' argument to find to only look for files. 2) when doing the ls use 'ls -ld' to restrict the ls to just showing the dirname and not the contents of the directory.

Hi,

what about:
find /directory -mtime -1 -print
?

Michael

[Michael Schulte zur Sur]

Oops,

should be:
find /directory -mtime -1 -type f -print

[Pete Randall]

Ahhh, but Michael, that's the problem as originally described:

"the find command looks like it uses the 24 hour break"

Hi Pete,

"the find command looks like it uses the 24 hour break"

I am sorry, but this eludes my English. ;-)
You forget, me German! ;-))

What does it mean?

Michael

[Pete Randall]

Michael,

Loosely translated, it means that -mtime +1 will match files created between midnight yesterday and midnight the day before. James was looking for a solution that would identify only the files created within the last 24 hours: from 7:00 AM this morning to 7:00 AM yesterday morning.

Hope that helps!

Hi Pete,

I understood so.

He, that is able to read, is in the advantage! If you read carefully my post, you will notice, that I said -mtime -1 and not -mtime +1. :^)

-mtime -1 gets all files younger than 24h

Hi,

As an alternative to the suggestions already made, you could use fbackup to take a full backup of your indexes, then use the incremental function of fbakup to get only the changed (or new) files.

See man fbackup.

Mark

Thanks Marc, I am a administrator for several HP servers and a bunch of Sun Solaris system running networker (the worse possible backup solution you could use), I love the fbackup and frecover of the HP-UX systems.
