Not sure if your script need be run regularly. Do you need the backup between 5am ~ 8am? If it is, to put it in cronjob will be good idea, with that you needn't change your code if the time is changed in the future. For example, the backup time is changed.
Hello all,
I would be happy if any one could help me with a shell script that would determine all the processes running on a Unix server and post a mail if any of the process is not running or aborted.
Thanks in advance

EXPIRE_BACKUPS(1) S3QL EXPIRE_BACKUPS(1)NAME
expire_backups - Intelligently expire old backups
SYNOPSIS
expire_backups [options] <age> [<age> ...]
DESCRIPTION
The expire_backups command intelligently remove old backups that are no longer needed.
To define what backups you want to keep for how long, you define a number of age ranges. expire_backups ensures that you will have at least
one backup in each age range at all times. It will keep exactly as many backups as are required for that and delete any backups that become
redundant.
Age ranges are specified by giving a list of range boundaries in terms of backup cycles. Every time you create a new backup, the existing
backups age by one cycle.
Example: when expire_backups is called with the age range definition 1 3 7 14 31, it will guarantee that you always have the following
backups available:
1. A backup that is 0 to 1 cycles old (i.e, the most recent backup)
2. A backup that is 1 to 3 cycles old
3. A backup that is 3 to 7 cycles old
4. A backup that is 7 to 14 cycles old
5. A backup that is 14 to 31 cycles old
Note If you do backups in fixed intervals, then one cycle will be equivalent to the backup interval. The advantage of specifying the age
ranges in terms of backup cycles rather than days or weeks is that it allows you to gracefully handle irregular backup intervals.
Imagine that for some reason you do not turn on your computer for one month. Now all your backups are at least a month old, and if
you had specified the above backup strategy in terms of absolute ages, they would all be deleted! Specifying age ranges in terms of
backup cycles avoids these sort of problems.
expire_backups usage is simple. It requires backups to have names of the forms year-month-day_hour:minute:seconds (YYYY-MM-DD_HH:mm:ss) and
works on all backups in the current directory. So for the above backup strategy, the correct invocation would be:
expire_backups.py 1 3 7 14 31
When storing your backups on an S3QL file system, you probably want to specify the --use-s3qlrm option as well. This tells expire_backups
to use the s3qlrm command to delete directories.
expire_backups uses a "state file" to keep track which backups are how many cycles old (since this cannot be inferred from the dates con-
tained in the directory names). The standard name for this state file is .expire_backups.dat. If this file gets damaged or deleted,
expire_backups no longer knows the ages of the backups and refuses to work. In this case you can use the --reconstruct-state option to try
to reconstruct the state from the backup dates. However, the accuracy of this reconstruction depends strongly on how rigorous you have been
with making backups (it is only completely correct if the time between subsequent backups has always been exactly the same), so it's gener-
ally a good idea not to tamper with the state file.
OPTIONS
The expire_backups command accepts the following options:
--quiet
be really quiet
--debug
activate debugging output
--version
just print program version and exit
--state <file>
File to save state information in (default: ".expire_backups.dat")
-n Dry run. Just show which backups would be deleted.
--reconstruct-state
Try to reconstruct a missing state file from backup dates.
--use-s3qlrm
Use s3qlrm command to delete backups.
EXIT STATUS
expire_backups returns exit code 0 if the operation succeeded and 1 if some error occured.
