For PGP
First download my Public PGP key from the download page or
HERE
then download the pgp signature file
for the file you wish to verify. Then run the following command Replace CURRENT-VERSION
with the
version you are trying to verify i.e. 0.98b.1
% pgp -ka ShawnScott.asc
% pgp ESR-Backup.CURRENT-VERSION.sig
For MD5
Most unix and linux systems have a program called md5 or md5sum if you don't
have this it is included in the GNU
Text Utilities
you can get the MD5 Checksum by typing the following. Replace CURRENT-VERSION
with the
version you are trying to verify i.e. 0.98b.1
%md5 ESR-Backup.CURRENT-VERSION.tar.gz
or
%md5sum ESR-Backup.CURRENT-VERSION.tar.gz
It will produce the checksum which will look like this
79292fd4113c598c12bb23a8438b69a7
If your result matches the checksum on my site you know you have a good copy. If it does not, please post a message on the ESR Backup Google Group
Yes there is, you simply delete the file called flist.dat in the data directory,
this will force ESR Backup to
do a full backup and recreate the file. It will then continue on it's regular
schedule on the next run.
No, absolutely none, if you lose your key you WILL NOT be able to recover and
archives you
encrypted with that key. You should always make multiple backups of your key
and keep
then in a secure place.
Absolutely, I love to hear suggestions and feature requests, I also want to
know about any bugs you find so
they can be fixed. Send and Suggestions, Bugs, Feature requests, etc to the
ESR Backup Google Group
It is not recommended that you do this. ESR Backup was written to be run on a daily basis. If it is run more than once a day the last Incremental or Full backup will be over written with the new one. ESR Backup was written to be simple and easy to use. Adding the feature to run a backup multiple times a day would require additional configuration and added complexity. I am currently working on a development release which will allow many more features including the ability to run multiple backups in a 24 hour time frame, flexible backup schedules and the ability to perform differential backups. Once this code is ready for a test release it will be posted in the download section.
Is there any daily administration that needs to be done on my backups?
ESR Backup takes a lot of the pain out of daily backups, It automatically sets a backup schedule, rotates your backups and stores your archives offsite. However you should periodically review the backup logs for errors , and never route the cron output of ESR Backup to /dev/null, ESR Backup only prints output if it has a problem or error. If it produces any output cron will automatically e-mail you a copy of the output. You should make sure the mail system is working correctly so you will be alerted to any problems or errors that may arise. You should also periodically verify and review your backups, to do this retrieve the last Full or Incremental backup that was performed if you use encryption use the decrypt-archive.pl script included in the ESR Backup package to decrypt your archive like this
Assuming the following
Key file is located at - /usr/local/keys/my.key
Archive is in the current directory
%decypt-archive.pl -K/usr/local/keys/my.key -A./Thursday-3-4-2004-Full-SHAWN.tar.gz
Once this has completed or if you are not using encryption you can view the contents of the archive with the following command
%tar -tzvf Thursday-3-4-2004-Full-SHAWN.tar.gz | more
This will print out a listing of all the files included in the archive. This listing can then be compared to your file-list.cfg to be sure you are getting complete and useful backups.
Back to TopWhy is ESR Backup set to perform a Full backup on Monday and Sunday?
As of version 1.0 you can now configure the day and type of backup per day from the configuration file.
