Topic: [Announce] smeserver-backup2 alpha release

[dmay]

HIGHLY experimental! For testing purposes only.

http://mirror.contribs.org/smeserver/contribs/dmay/smeserver/7.x/smeserver-backup2-0.0.1-a2dmay.noarch.rpm

This is an initial merging of backup2ws/usb into one single contrib. I have also been extensively rewriting the code to ConfigDB format. This is completed for action scripts and initially started for the panel. At some point the panel needs to be rewritten into FormMagick.

Note this contrib obsoletes and removes backup2ws/usb rpms and files. It will leave the associated dbs which should be manually deleted at your discretion.

I have built and began initial testing on 7.x only. I believe this will not work on <7.x but have not tested. Released early for others to try. Feedback appreciated.

Hi Darrell,

Testing alpha 4 with backup2usb, regular backup & 911.  Have not run a test restore yet, but wanted to pass the following on to you.

1 - Running 911 Job - "Cannot open /etc/smbpasswd"
Here is the log:

Jan 20 21:35:40 server2006 e-smith-bg: Cannot open /etc/smbpasswd
I wouldn't think /etc/smbpasswd would have anything to do with a locally-attached usb disk (but I could be clueless here).
2 - USB Disk time to umount after backup log has added all files (according to log).
I have noticed that it takes awhile for the usb disk to umount.  Could it be that backup2 is still compressing the files?  I am still using default compression 3.  I'll try a 0 to see if the disk umounts any quicker.
This is being run on a Dell PowerEdge 500SC, 1.15Ghz processor, two 7200 rpm disk raid 1 (separate ide channels), top reports 645.7MB of RAM.

Thanks for the great work.

Same results.  911 takes about 5 minutes to run.  The 911 post-processing runs very quickly.  I'm waiting on something here.

I'll test with a larger backup and see if the timing is any different.

"Cannot open /etc/smbpasswd"

/etc/smbpasswd does not exist in a fresh install of 7.0pre1 as samba conf files have moved to /etc/samba/smbpasswd. IIRC if you upgrade from previous SME releases you may have a linked file /etc/smbpasswd to /etc/samba/smbpasswd. I also note that the generic SME Server backup panel also attempts to backup both sources. See /usr/lib/perl5/site_perl/esmith/Backup.pm. I decided to also include both file locations in the DisasterRecoverySource. The result is a non-critical log error if the file/link does not exist. Easy for anyone to change by editing via the panel and dropping /etc/smbpasswd if it does not exist on your server. I will most likely drop this from the default source sometime in the future.

USB Disk time to umount after backup log has added all files.

The script simply issues the standard umount command. How long it takes to unmount is up to your server to process the command. Good be a lot of things. Hardware, ext3 journalling completing, your mount point choice and fstab entries, any external command accessing the mount point during umount?

Thanks for the feedback.
